How similar the debates surrounding Munich’s Max-Joseph-Platz and Vienna’s Michaelerplatz are: The central and listed squares are to be redesigned to make them climate-friendly. Some call it an important contribution to climate protection, others fear that it will be too intrusive and destroy the appearance of the respective ensemble.

Cities such as Munich and Vienna groan under hot temperatures in summer, and so do their residents. It is clear to everyone that things cannot go on like this! An effective way to reduce the heat in cities is to unseal them – in other words, gray stones should give way to green plants. To gain more green spaces, squares are welcome areas in cities, as they are usually large and often at least traffic-calmed. At the same time, green squares can not only have a positive effect on the urban climate, but also offer a space for spending time outdoors – increased quality of stay is the popular keyword here. Everyone agrees that such squares are needed. However, the choice of squares sometimes meets with resistance – as is the case in Munich and Vienna. Experts in both cities criticize the fact that monument protection cuts corners when it comes to measures to improve climate protection. Both city councils have improved their plans as a result, but the squares are still being changed.

Max-Joseph-Platz in Munich is located at the end of Maximilianstraße and was designed by court architect Leo von Klenze (1784-1864). Klenze based his design on the Capitol Square in Rome. The square is surrounded by important buildings. In 1811, the National Theater was built here by Karl von Fischer (1782-1820), modeled on the Odeon in Paris. Between 1825 and 1842, during the reign of King Ludwig I (1786-1868), the royal residence was built on the north side of the square. The architect responsible was Leo von Klenze, who designed the building in the classicist style based on the models of the Florentine palaces Palazzo Pitti and Palazzo Rucellai, which still characterize Max-Joseph-Platz today. Opposite the Königsbau is the Palais Toerring-Jettenbach, which was built between 1747 and 1754 in the Rococo style by Ignaz Anton Gunetzrhainer (1698-1764). Klenze adapted the building and thus integrated it into the overall ensemble, using the Ospedale degli Innocenti in Florence as a model.
The center of the square is dominated by a monument to Maximilian I Joseph of Bavaria (1756-1825). The Max Joseph monument, which shows the king in a seated position, was created by the sculptor Christian Daniel Rauch (1777-1857) in collaboration with Leo von Klenze and the ore caster Johann Baptist Stiglmaier (1791-1844) between 1826 and 1835. The monument is surrounded by a paving consisting of coarse Isar stones. The square is to be redesigned to provide Munich residents with a replacement for the green space at Marienhof, which will not be there for several years due to the expansion of the second S-Bahn main line. This ground covering was originally to be replaced by shrubs, grasses and wildflowers. Following the rejection of the design by the State Monuments Office, the plan was changed. Matthias Pfeil, the head of the Bavarian Monument Preservation Office, criticized the plans in an interview with the Süddeutsche Zeitung. His main criticism was that the plans were too simple and made no reference to the history of Max-Jospeh-Platz. The square deserved an effort, he said. At the same time, however, he also showed understanding for the approach of wanting to change the square and described it as “misused” by simply using it as a traffic area. Another detriment to the square is an underground car park that was built on the site in the 1960s.
Following criticism from the Office for the Preservation of Historical Monuments, the plans were adapted. They were based on plans from 1825, which were found in the main state archive. Now a grassy roundel, interspersed with gravel paths, is to surround the monument and green Max-Joseph-Platz. The paths are to run towards the monument in a star-like and strictly geometric pattern. The square will also be flanked by shrubs planted in planters. According to the Monument Preservation Office, however, this is to be an interim solution. According to reports in the Süddeutsche Zeitung, it is also planned that the entrance to the underground car park will be narrower towards Maximilianstrasse. If the conservationists have their way, the underground car park will also be removed in future.

The greening of Michaelerplatz in Vienna is not planned as an interim project like Max-Joseph-Platz. The square, which is surrounded by the Hofburg Palace, St. Michael’s Church and the Looshaus, is also to be made more attractive with greenery, according to the City of Vienna. Conservationists and art historians from Austria and abroad have criticized this plan in an open letter. In the letter, which can be read on the website of the Austrian Society for Architecture, you can read, among other things, that nobody would think of planting trees in the Piazza Navon in Rome, the Grand-Place in Brussels or the Domplatz in Salzburg. The authors of the letter emphasize that on Michaelerplatz you could experience the most important phases of Vienna’s history, from antiquity, through the Middle Ages and Baroque to modern times. The square is also home to icons of architectural history: in addition to the building by Adolf Loos (1870-1933), there is also the Michaelertrakt, designed by Joseph Emanuel Fischer von Erlach (1693-1742). The overall design of the square goes back to Hans Hollein (1934-2014), dates from the 1990s and is also a listed building. In addition, the square in its current design is also part of the UNESCO World Heritage Site.
The first draft envisaged raised beds, trees and water features. The plans also included removing the paving stones. Cyclists in particular welcomed this. The Federal Office for the Preservation of Monuments initially approved the plans, but there was also criticism within its own ranks. The Austrian Advisory Council on Monuments also expressed reservations about the plans. The idea of planting bluebell trees met with particular criticism. These fast-growing trees have an aggressive root system, which would particularly endanger the historical excavations located on the site, which can also be visited there. However, it is still uncertain whether those responsible will nevertheless have this type of tree planted or whether other trees will be chosen. The politicians have already made improvements in some areas. The raised beds have been replaced by flat beds and the planned water features in front of the Loos House have apparently been completely removed. The signatories of the open letter expressly emphasize that they welcome the City of Vienna’s efforts to adapt to climate change, but they also stress that the “effect of the historic ensemble” is being destroyed at this point. They also suggest that a final sealing of Heldenplatz or the greening of city districts, which would benefit the residents, would be a better solution.
In general, one can also ask whether greening Michaelerplatz is necessary at all. After all, both the Burggarten and the Volksgarten are just a five-minute walk from the square. This question is also justified in Munich. After all, the Hofgarten is only a stone’s throw away from Max-Joseph-Platz. The English Garden can also be reached quickly from there.

Romans in architecture: antiquity meets modern planning? It sounds like a museum topic for Latin teachers and amateur historians, but it’s actually very topical – at least for architects who know that a Roman water pipe has more digital relevance than some BIM consultants would like. Roman architecture is not a nostalgia trip, but a lesson in sustainable technology, robust urban planning and visionary choice of materials. Anyone building, planning or developing cities today can learn more from the ancient Romans than from many an innovation agency. But what is really behind the myth of “Roman architecture”? And what does the renaissance of antiquity look like in the age of BIM, AI and sustainability certification?

  • Roman architecture is much more than columns and triumphal arches – it was a blueprint for functional, sustainable and resilient buildings.
  • In Germany, Austria and Switzerland, ancient techniques can be found in a surprising number of modern projects.
  • Digital tools such as BIM and AI make it possible to reanalyze and further develop Roman building principles.
  • Sustainability was not a buzzword for the Romans, but an engineering necessity – and provides valuable impetus today.
  • The examination of Roman architecture demands technical know-how and cultural maturity from today’s planners.
  • The debate surrounding the return of ancient principles is not free of criticism – there is a fierce debate between reconstruction, retro design and genuine innovation.
  • Global architectural trends such as cradle-to-cradle, urban mining and low-tech construction draw on Roman ideas.
  • The future lies in dialog: Antiquity meets algorithm, brick meets digital twin, city wall meets smart city.

Ancient architecture: foundation of modernity or museum relic?

Anyone walking through Cologne, Trier or Vienna today will stumble across Roman walls, amphitheatres and water pipes – often embedded in the modern cityscape, sometimes lovingly museumized, occasionally carelessly built over. But the influence of the Romans on architecture does not end with picturesque ruins. Rather, the civil engineers of antiquity worked with techniques, materials and urban structures that still occupy us today. Roman architecture was radically functional, uncompromising in its use of materials and – it has to be said – surprisingly sustainable. Roman concrete, for example, the famous opus caementicium, still holds up today where some of the exposed concrete of post-war modernism has long since crumbled. This is not folklore, but a tangible technological advantage that modern materials researchers are now trying to decipher using high-tech methods.

In Germany, Austria and Switzerland, the study of Roman architecture is by no means a niche topic. From the reconstruction of entire city quarters in Augusta Raurica to the integration of Roman floor plans in current projects in Trier and experimental research into ancient mortar formulas at ETH Zurich – the dialog between antiquity and the present is alive and well. But it is more than mere imitation. Modern planners draw inspiration from the Romans for clever water management, intelligent traffic routing and durable material concepts. The Romans not only invented the wheel, they also integrated it properly into urban planning. What is sold today as “smart mobility” was part of everyday life in Rome – including car sharing, at least for horse-drawn carriages.

The question is: why is this even interesting? Quite simply because the challenges have remained the same. Scarcity of resources, climate change, urbanization, infrastructural resilience: all of these were already on the minds of the Baumeister of antiquity. Anyone who thinks that digital bells and whistles and green certificates have reinvented the wheel today should take a look at the Roman aqueducts. These are not only monuments in stone, but also data sources for the sustainable construction of tomorrow. You just have to be able to read them.

Of course, there are also skeptics. For many, Roman architecture is just a retro backdrop or a Disneyland aesthetic. But the truth is that behind the stone façades lies a systems thinking that comes surprisingly close to today’s digitalization. The Romans planned their cities as networks – with nodes, redundancies and feedback loops. Anyone who ignores this is missing the opportunity to learn from 2000 years of architectural history. And not for the next museum, but for the next smart city.

The conclusion of this section: Roman architecture is neither a dusty relic nor a mere source of inspiration for retro trends. It is a foundation, mirror and sometimes also a provocation for contemporary architecture. Anyone who dismisses it as museum folklore has already lost the game. Those who interpret it wisely can fundamentally shape the future of architecture.

Innovation through tradition: digital tools meet ancient principles

It sounds paradoxical: digitalization, of all things, has sharpened our view of Roman architecture. While in previous decades, ancient architecture was primarily deciphered by archaeologists, today it is BIM models, simulations and AI-supported analyses that make ancient structures, material structures and construction principles visible. Modern laser scans reveal how the Romans layered walls or constructed vaults. Digital twins of ancient buildings make it possible to simulate load scenarios, understand material fatigue or calculate the effect of earthquakes on the Pantheon. This is not an end in itself, but provides concrete impetus for modern building and infrastructure construction.

In Germany, Austria and Switzerland, cooperation between construction research, digitization experts and architecture firms is increasing. ETH Zurich, for example, is digitizing Roman buildings in order to derive new construction methods for sustainable bridges or domed structures. In Trier, digital models of Roman temples are being used to develop structural optimizations for current church buildings. And planners in Vienna are using simulation tools to test ancient city districts for their urbanity today. The interface between antiquity and algorithms has long been part of everyday business for innovative planners.

Of course, technology is not an end in itself. The decisive factor is how digital tools translate the findings of antiquity into practice. Anyone who only uses BIM models to render Roman columns is missing the point. It’s about understanding material cycles, extending life cycles and developing resource-saving constructions. The Romans were masters of upcycling – without any certificates. Their example shows: Digitalization makes sense when it combines tradition and innovation instead of playing them off against each other.

At the same time, the discourse is not free of criticism. The danger of trivialization is real: antiquity as a pure rendering gimmick, as “render porn” for Instagram and architecture faculties, doesn’t help anyone. It requires technical depth, a willingness to research and a willingness to engage with the original. Those who manage this can actually create innovation through tradition – and redefine building culture digitally.

The bottom line is that the combination of digital tools and ancient principles is not fashionable hype, but a necessary strategy for sustainable architecture. Anyone who ignores the potential of the Romans in the digital age is building past reality – in the truest sense of the word.

Sustainability: Roman architecture as a model and a challenge

Roman architecture was never an end in itself. It served one goal: to build cities that function, last and use resources efficiently. Sustainability was not a marketing slogan, but a question of survival. The Romans used locally available materials, planned buildings on a modular basis and focused on durability. Their mortar was not only robust, but also self-healing, and their water pipes could withstand thousands of years. Anyone talking about the circular economy, urban mining or low-tech construction today is not inventing anything new – they are building on Roman principles.

The challenges of the present are similar, and the solutions are often surprisingly Roman. In Switzerland, ancient quarrying methods are being rediscovered in order to build more sustainably. In Germany, Roman mortar recipes are being tested for restoration and new construction. In Austria, the layouts of Roman cities serve as a model for smart neighborhood developments that make optimal use of wind, water and sun. The highlight: Roman sustainability is always systemic – never as an individual measure, but as an integral part of urban planning.

Of course, this revival also has its limits. Ancient techniques cannot be transferred one-to-one. The Roman brick is no substitute for the passive house standard, and an aqueduct does not solve every urban infrastructure problem. But the principles are universal: durability, reparability, flexibility, contextual relevance. If you take this seriously, you can bring real sustainability into the 21st century with Roman ideas. But only if they take them further – with the latest technologies, digital planning and new materials.

There is also plenty of criticism. Some see the return to antiquity as an escape from technical innovation – a retreat into the historical because the present seems too complex. But the opposite is the case: anyone who takes Roman sustainability seriously today is facing up to the hardships of reality. After all, sustainable building does not mean doing without, but cleverly integrating old and new. This is exactly what antiquity teaches us – and this is exactly what we need in view of the climate crisis and lack of resources.

Conclusion: sustainability is not the exclusive domain of modernity. The Romans showed us how to achieve great things with limited resources. Those who understand the principle and combine it with digital know-how can create architecture that is truly sustainable – and not just for the certificate.

Job profiles and controversies: what remains of the Roman legacy?

The return of ancient principles to contemporary architecture is more than just an aesthetic trend. It is changing job profiles, demanding new technical knowledge and provoking debates about the core of building. Anyone working as an architect, civil engineer or urban planner today must not only know Roman architecture, but understand it. Material science, historical analysis, digital modeling and sustainable planning are merging into a new professional profile. The demands are increasing, the projects are becoming more complex – and looking back is becoming a driver of innovation.

But the debate is controversial. Some architects see the renaissance of ancient principles as a threat to their own creativity. They fear the banalization of building culture, the slide into pseudo-reconstruction and retro kitsch. Others celebrate antiquity as a universal reference, as an inexhaustible source of inspiration for sustainable and functional architecture. As is so often the case, the truth lies somewhere in between. It takes technical know-how, critical thinking and a willingness to combine the old and the new.

Another contentious issue: who decides how much antiquity is allowed in modern construction? The preservation authorities? The investor? The politicians? The answers differ in Germany, Austria and Switzerland – and the dispute over reconstruction, contemporary interpretation and cultural identity is far from over. But one thing is clear: the debate about Roman architecture is forcing the industry to ask itself fundamental questions. What is authentic? What makes sense? What is sustainable?

Roman heritage also plays a role in the global discourse. International architecture competitions, research projects and sustainable building initiatives draw on ancient principles – from China to California. The Romans have long been part of the global architectural debate, whether as a role model, a warning or a provocation. Anyone planning internationally today cannot ignore them.

To summarize: Roman architecture is not only part of our cultural heritage, but also an active driver of innovation, criticism and further development. It changes the industry, demands new skills and remains a touchstone for the quality of contemporary architecture.

Outlook: Antiquity and the future – dialog instead of dogma

Antiquity is not a dogma, but a dialog partner for the architecture of the future. Anyone building today cannot rest on the laurels of tradition or retro aesthetics. It is about understanding Roman principles, interpreting them digitally and developing them sustainably. The combination of ancient architecture and modern planning is not a contradiction – it is a necessity. Material research, digitalization, sustainability and cultural identity are merging to create a new understanding of architecture that combines the strengths of the past with the opportunities of the present.

The challenges are considerable. Climate change, scarcity of resources, urbanization, technical complexity – all of these call for new answers. The Romans do not provide ready-made solutions, but they do demonstrate principles that are relevant again today: Systemic thinking, robust constructions, flexible urban planning and sustainable materials. Those who supplement this with digital tools create architecture that lasts – not only aesthetically, but also functionally and ecologically.

Of course, the debate remains open. Anything is possible between reconstruction and innovation, between retro kitsch and radical reinterpretation. What is crucial is that the industry has the courage to engage in a dialog with antiquity – critically, technically sound and open to new ideas. Those who manage to do this can not only learn from history, but also continue it.

Germany, Austria and Switzerland are on the right track, even if there is still a lot of skepticism and uncertainty. Cooperation between research, practice and the digital economy offers opportunities to make productive use of the Roman legacy. The global architecture world is looking closely – and expects impulses, not quotes.

The bottom line is that the future of architecture is hybrid. Antiquity meets algorithms, knowledge meets tools, history meets innovation. Those who understand this not only build houses, but also write history – without sandals.

Conclusion: The Romans were the first real “Baumeisters”. Their legacy is not museum ballast, but a treasure trove of sustainable, digital and functional architecture. Anyone building today should listen to them – and contradict them where necessary. This is the only way to create architecture that not only endures, but also creates the future.

Siemens Mobility: Upgrade for Montreal’s public transportation system

Building design

Upgrade for Montreal’s public transportation system: Siemens Mobility has been awarded the contract to manufacture and commission ten Charger locomotives.

Siemens Mobility has received an order from the Montreal transportation company Exo to develop, manufacture and commission ten Charger locomotives. This is the company’s second order for Charger locomotives in Canada. It will replace the older locomotives in the Exo fleet with a fuel-efficient and environmentally friendly locomotive. Read more here.

Siemens Mobility has been awarded a contract by Montreal’s Metropolitan Transportation Network Exo to design, manufacture and deliver ten new Charger locomotives. These environmentally friendly trains will replace older locomotives and ensure more sustainable public transportation in the Canadian city. Their modern technology will increase the availability of the trains.

This is the company’s second order for Charger locomotives in Canada. The trains meet the country’s strict Tier 4 emissions regulations. Charger locomotives are not only less CO2-intensive, but also quieter, which increases passenger comfort.

In addition to the manufacturing contract, Siemens Mobility has offered the option for a spare parts supply contract. “We are excited to partner with Exo and look forward to working with them to modernize their fleet with the latest sustainable and intelligent rail technology,” said Yves Desjardins-Siciliano, CEO of Siemens Mobility in Canada. “Our industry-leading locomotives will provide Exo and its passengers with a sustainable travel option as well as a pleasant, safe and reliable travel experience. This important project builds on our work to help Canadian cities improve their public transit infrastructure to meet growing transportation demand in a modern, safe and sustainable way.”

The Charger locomotives are known for their low fuel consumption. They can run on biodiesel and meet strict regulations, making them the “most sustainable passenger locomotive in the industry”, according to the company. The locomotives are characterized by a 95 percent reduction in particulate matter and an 89 percent reduction in emissions compared to Tier 0 locomotives.

In total, Siemens Mobility has ordered more than 300 Charger locomotives since 2010. 95 of these are currently in operation, making them the market leader in the Tier 4 locomotive segment. In addition to customers in Canada, there are also many interested parties in the United States. The states of California and Washington have already added Charger locomotives to their fleets.

The ultra-modern trains are powered by a 4,400 hp Cummins QSK95 diesel engine. They can travel at speeds of up to 125 miles per hour (201 km/h). The trains were also the first high-speed passenger locomotives to receive the Environmental Protection Agency’s Tier 4 emissions certification. This US Tier system is also used in Canada.

Siemens Mobility in Canada

Siemens Mobility has been supporting the Canadian transportation industry for more than 40 years. For example, the company has supplied light rail vehicles in Edmonton and Calgary as well as modern trains for VIA Rail. The company was also involved in the electrification of the Kitchener-Waterloo light rail system and the signaling and train control of the Trillium line in Ottawa.

Recently, Siemens Mobility Canada acquired the Canadian rail service provider RailTerm, adding nearly 200 employees to its growing team in the country. The company currently has 24 offices in Canada with more than 2,500 employees. About 700 of them work in Québec.

Siemens Mobility is a separately managed company from Siemens AG. It positions itself as a leading provider of transportation solutions with an innovative portfolio. Its core areas are rail vehicles, rail automation and electrification, turnkey systems and related services. Another focus is on intelligent infrastructure, which increases the sustainability of value creation, enhances passenger comfort and ensures availability. Environmentally friendly solutions are also part of the offering.

In fiscal year 2021, Siemens Mobility generated sales of €9.2 billion with almost 40,000 employees worldwide.

The Montreal exo-network

Montreal’s public transportation system, which also serves areas in the surrounding metropolitan area, is known as Exo or officially as Réseau de transport métropolitain, RTM. The agency was founded in June 2017 and has since grown to become the second largest public transit system in Canada after Toronto’s GO Transit. Exo focuses on commuter trains as well as city buses.

Exo’s trains and buses serve a population of approximately 4.1 million people with more than 750,000 daily trips. This includes the operation of commuter trains in Montreal. The data-driven company is positioning itself as part of Montreal’s smart city network. The order of ten Charger locomotives is part of Exo’s efforts to provide the best and most sustainable service for its customers.
