The Olympic triathlon dress rehearsal for Paris 2024 took place a week ago. The participants were supposed to compete in the swimming part of the event in the Seine. However, the dress rehearsal literally fell through: contaminated water due to a defective wastewater valve and dead rats led to health risks, which is why the triathlon became a duathlon without swimming. During practice, some athletes experienced gastrointestinal complaints and E. coli bacteria were discovered.

Rio de Janeiro faced a similar problem at the 2016 Olympic Games, when contaminated water in the sailing area led to canceled competitions. Water samples are usually taken before a triathlon, as is the case in Paris, although it is not always clear where in the water the samples are taken.

Nevertheless, the city of Paris aims to hold open water competitions of the Olympic Games in the Seine in 2024. Although swimming in the river has been banned since 1923, the idea of swimming in the middle of the French capital is appealing. When the Olympic Games were held in Paris in 1900, it was still possible to swim in the Seine. At the second event in 1924, swimming had to take place indoors. In addition to Olympic competitions, the Seine is to be opened to the public for swimming in some places from 2025.

Like every major river in a city, the Seine in Paris is a popular recreational area. The city has already invested 1.4 billion euros in the greater Paris area to open up the Seine. This requires thousands of households and hundreds of houseboats to be connected to the sewage system. It is also necessary to build and modernize sewage treatment plants. Catch basins are planned for the Summer Olympics in order to guarantee the water quality of the river even when it rains. This is because wastewater from the overloaded sewage system can overflow into the river during heavy rainfall.

Currently, the water quality of the Seine is heavily dependent on the weather. The new infrastructure should guarantee good quality regardless of the weather.

One of the three places where it should be possible to swim in the Seine in future, even without an Olympic qualification, is not far from the Eiffel Tower. Another site is a water sports center that is already used for leisure activities on the Seine. And according to Paris Mayor Anne Hidalgo, the third site is also to be centrally located. All the water areas concerned are to be separated by buoys and accessible via a footbridge. Areas for changing and showering are also planned.

For several years now, swimming in the Seine has been possible in a floating outdoor pool. However, this consists of a separate pool that is anchored in the water. Accordingly, chlorinated water is currently used instead of river water. Jacques Chirac, president from 1995 to 2007, promised Parisians that they would soon be able to swim in the Seine again.

Now, 102 years after the ban on swimming, the three planned bathing areas, a legacy of the Summer Olympics, are set to fulfill this promise. The water quality was already poor in 1923. There was also concern about the increasing boat traffic, which could be dangerous for swimmers. So far, Paris’ investments have been largely successful and the water is safe for swimming 90 percent of the time, according to the city. Regular tests should guarantee this in the future.

In view of the consequences of climate change and predictions of increasingly hot summers, a swimmable Seine will not only make the French capital more attractive, but also more climate-resilient. Because when the summer weather reaches 40°C, or perhaps even 50°C from 2050, cooling off will be worth its weight in gold.

Despite the failed triathlon attempts in August 2023, Paris is on the right track as far as the water quality of the Seine is concerned. Samples taken on 6 June and 19 July showed values that were suitable for swimming according to World Health Organization guidelines. Due to heavy rainfall in August 2023, the water quality has recently dropped again.

The city plans to continue testing regularly and implement appropriate measures to clean up the Seine. Since the early summer of 2023, there have been two water treatment plants on the Seine and the Marne. And a new storage basin called Austerlitz can store over 50,000 cubic meters of water. So if it rains heavily shortly before next year’s Summer Games, wastewater can be fed into the sewage system and treatment plants via the storage basin instead of polluting the Seine.

There will also be alternative dates for the competitions in the water, just in case. Depending on the water quality, it should be possible to hold competitions at a later date if necessary. This shows that the city of Paris is not yet entirely sure about the water quality in 2024.

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.

“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!
