Like every host city of the Olympic Games, Paris is also trying to create a legacy in the form of a transformation project. In the French capital, sustainability is to take center stage this summer. To this end, Paris is relying on flexible, reusable wood instead of magnificent monuments.

One of the key features of the 2024 Summer Olympics and Paralympics is that not much is actually being built. 95 percent of the required Olympic venues already exist. And the new structures rely heavily on sustainable materials such as reusable wood. The most important architectural symbol of the Paris 2024 Summer Games will be the Olympic Swimming Center in Saint-Denis.

The largest wooden structure in the world is currently located there. It consists of 1,500 cubic meters of European spruce. The architecture firms Ateliers 2/3/4 and VenhoevenCS designed the eye-catching building with its Pringles-shaped solar roof. They assembled the solid, glued timber construction like a Lego set. “We wanted to use as little material as possible, and wood means that we don’t need any additional material to cover structural elements during construction,” says Laure Mériaud, partner at Ateliers 2/3/4/.

Host cities of the Olympic Games are not only hoping for international attention and tourism, but also urban transformation. Barcelona planned a new beach promenade for 1992, Athens expanded its metro system for 2004 and London completely redesigned a derelict site for 2012. In Paris, the aim is to set an example for sustainability. This transformation is less grandiose, but all the more important for that. By only building a few new structures overall, the city is showing that even major events such as the Olympic Games can have a moderatecarbon footprint.

The new projects include the Olympic Village in the north of Paris, which is intended to be an eco-district. Here, too, wood takes center stage: the buildings are made of wood and glass and obtain their sustainable energy from heat pumps. The 8,000-seat Champs de Mars arena also consists of a solid glued wood support structure. With a recycled aluminum façade, this building will serve as a center for the Paris basketball team and also offer two public sports halls.

Probably the biggest example of the sustainable 2024 Summer Olympics is the new indoor swimming pool being built in Saint-Denis. The large wooden building will be perhaps the only architectural icon of the Olympic Games. The architects plan to leave the wood in its natural state to add charm. “We don’t have to paint it. It has warmth, it has color and it has a scent. You can smell it when you’re in the pool,” says Laure Mériaud.

Much of the wood used for this indoor swimming pool comes from Alsace, near the German border, where it was also assembled. Using the Lego principle, the architects planned to assemble the prefabricated individual parts in Saint-Denis. The debate focuses not only on wood as a building material, but also on the origin of the building material. It comes from a sustainably managed forest. With its natural insulating properties and carbon storage function, wood is therefore a sustainable, environmentally friendly building material.

Sustainable wood also plays an important role in the other Olympic projects in Paris. For example, all buildings in the Olympic Village that are less than eight storeys high must be made entirely of wood. The material is also to be preferred for taller buildings. The energy that supplies the village should also come from renewable sources and be distributed using heat pumps.

Paris is also thinking about social sustainability: Saint-Denis is an industrial area of Paris where many social problems are prevalent. But by locating both the iconic indoor swimming pool and the Olympic Village in this district, the organizers of the Games hope to bring about sustainable change. Well-known media and service companies are already settling in Saint-Denis to be at the center of the action. This center should continue to have a positive impact even after the Olympic Games. Both the indoor swimming pool and the Olympic Village are to remain and be made available for use by the residents of Saint-Denis.

With the approach of sustainable timber construction and the idea of repairing buildings rather than constructing new ones, France wants to use the Olympic Games as a springboard for a green transformation of the construction industry. The aim is to reduce carbon in the construction sector. With this in mind, existing structures across the country will be retrofitted for various purposes. The games will also serve as a showcase example of how wood can be used in new construction.

France is thus making an important contribution to the EU’s goal of reducing emissions in the region by 55% by 2030. In 2020, there was already a proposal for a law requiring all new public buildings to be made of at least half wood or other ecological materials. Unfortunately, this did not prevail, but it shows that the topic is very important in our neighboring country. Although the French timber construction industry is not as advanced as those in Austria and Germany, for example, France is ahead in the use of ecological materials. The government’s support and the beacon effect of the Olympic Games will help to ensure that wood makes the headlines as a sustainable building material.

Rising high above the Thuringian countryside, Wartburg Castle is one of the most representative cultural monuments in Central Europe. Since its inscription on the UNESCO World Heritage List, it has been one of the most outstanding testimonies to European history. Architecture, political events and literary tradition intertwine here to create a multi-layered cultural narrative.

The history of Wartburg Castle begins in the 11th century, when it was founded as the residence of the Ludovingian landgraves and from then on shaped the political power in the region. Even in the High Middle Ages, the palace, enthroned on a steep limestone cliff, was considered a masterpiece of late Romanesque architecture, whose design and ornamentation make it one of the most important secular buildings north of the Alps. This architectural heritage is evidence of the feudal character of Central Europe and forms one of the foundations for the later recognition as a World Heritage Site.
Wartburg Castle’s role as a center of courtly culture and memory grows through literary traditions such as the so-called Singers’ War, which was passed down in Middle High German poetry. At the same time, historical figures such as St. Elisabeth of Thuringia, whose life and work are closely linked to the castle, are becoming firmly established in the culture of remembrance. Even if some legends were mythically exaggerated, they still reflect the early symbolic value of the place in the cultural imagination.

The architectural appearance of Wartburg Castle is the result of a long development that underwent a profound transformation, particularly in the 19th century. After centuries of changing use and partial decay, the emerging Romantic period initiated a comprehensive restoration that was based less on a historically accurate reconstruction than on an idealized image of the Middle Ages. Under this premise, the Elisabeth Bower and richly decorated interiors were created, which today form an integral part of the complex.
From an art historical perspective, this combination of original 12th century parts and historicist additions is ambivalent: on the one hand, the preserved Romanesque building elements document the civil architecture of its time; on the other hand, the 19th century additions reflect the monument preservation and historical myths of the time. It was precisely this mixture of archaeological and symbolic authenticity that was taken into account in the UNESCO nomination, with the term “authenticity” not only referring to material originality, but also including the ideas and meanings anchored in the collective consciousness.

Wartburg Castle is more than just a stone relic – it is a place of profound cultural connections. Martin Luther’s stay here during his exile from 1521 to 1522, when he wrote the German translation of the New Testament from Greek in the so-called “Junker Jörg” room, was particularly influential. This achievement in the history of language had far-reaching consequences for theology, education and the German literary language as a whole and had a lasting impact on the cultural significance of the castle.
In the 19th and early 20th centuries, Wartburg Castle also became a symbol of national identity and political integration. Events such as the Wartburg celebrations of the German student movement became part of the collective memory, as did literary and musical adaptations in works by Richard Wagner, which romanticized the image of the medieval castle courtyard. Wartburg Castle also remains a living point of reference in cultural memory as an inspirational place for artistic debate.
In 1999, the site was inscribed on the UNESCO World Heritage List on the basis of two criteria: Firstly, as an “outstanding monument of the era of feudalism in Central Europe” (criterion (iii)) and secondly, as a site “rich in cultural references”, particularly emphasizing its connection to the history of the Reformation and the German unification movement (criterion (vi)). These criteria reflect the exceptional universal value that Wartburg Castle has beyond the borders of Thuringia. The castle not only documents the architecture and living environment of high medieval feudalism, but also exemplifies the profound influence of historical events and cultural upheavals on European civilization. The UNESCO designation therefore not only recognizes the material substance of the complex, but above all its role as a place of remembrance that inspires generations of visitors to reflect and research. The integrative perception of architecture, history and cultural impact makes Wartburg Castle a unique medium for communicating the past and present.
At a time when cultural heritage is increasingly being discussed in a global context, Wartburg Castle highlights the importance of historical sites as mediators of identity, memory and transnational understanding. Its place on the World Heritage List helps to secure this significance in the long term and make it tangible for future generations.

“Security” in architecture means more than just barriers and alarm systems – there is much more to it than that. This issue sheds light on how buildings can provide protection – be it against the forces of nature, theft or social conflict. Your planners do not see security as a restriction, but as a design potential. In order to avoid repellent gestures, they often find security-relevant solutions in the building form. […]

“Security” in architecture means more than just barriers and alarm systems – there is much more to it than that. This issue sheds light on how buildings can provide protection – be it against the forces of nature, theft or social conflict. Your planners do not see security as a restriction, but as a design potential. To avoid repellent gestures, they often find security-related solutions in the building design.

Security – a word that is supposed to reassure and yet often has the opposite effect. We all long for it, but we also know that there is no such thing as absolute security. A building can protect against rain and cold, a city can be well planned – but can architecture really guarantee that we feel safe? Or does it only create an illusion? And in the end, isn’t the feeling of safety just as important as the safety itself?

The last year alone has shown us once again how fragile our built and lived environment is. Collapsing bridges, poorly maintained high-rise buildings and natural disasters that destroy entire neighborhoods. At the same time, fear of attacks in public spaces is growing, and in many cities measures are being taken to turn urban squares and buildings into high-security zones. But do we really need to turn our built reality into bastions of concrete and cameras in order to feel safe? Or is there a more intelligent answer to the question of protection?

Architecture cannot guarantee absolute security, but it can create trust. It can shape spaces that convey a sense of security without restricting freedom. Architecture has the unique potential to master precisely this balancing act. From fire and earthquake-proof school buildings to carefully considered designs for public spaces: Security architecture must not rely solely on control and barriers, but must enable trust and freedom. A clever choice of materials, for example, can preserve a feeling of openness without sacrificing protection. Ultimately, it must not be about sealing things off, but about proactive design.

Security must not become an aesthetic of mistrust. Walls, bars, barriers and confined spaces may minimize risks, but they also separate us from each other. All too often, they stifle life. The most popular place, both inside and out, is often where people meet, where light and transparency dominate, where architecture acts as a social bond and thus serves a greater purpose.

This issue is an invitation to rethink security. We show projects that prove that protection does not have to mean control, but trust. That architecture not only erects walls, but also builds bridges – between security and freedom, between control and openness. Because true security is not created by fear, but by clever (re)planning, by courageous design and by a society that does not close itself off, but proactively takes the helm. Enjoy reading!
