« Tout garder/tout changer. Réparer et prendre soin des villes » Exhibition

À l’Ancienne Poste, 3 avenue de Paris, 78000 Versailles / Free admission
Tuesday to Friday: 12pm to 7pm and weekends: 11am to 7pm

The aim of “Tout garder/tout changer” is to share inventive and positive solutions for repairing and transforming cities and regions, adapting them to the effects of climate change, making them sustainable and thus finding the right balance.

As the philosopher Eileen Christ suggests, we can “celebrate the limits”. Nine narratives, illustrated by artist Coline Hégron, offer an deep dive into repaired worlds, revealing territorial, architectural, urban planning and landscape projects that respond to major contemporary challenges: The scenography, designed by Atelier +1 and studio lebleu, creates itineraries and furnishings made from the doors of the rooms in the Athletes' Village at the 2024 Olympic Games, which have been repurposed in the pavilion before being given a third life. The exhibition also offers an iterative work to be built together, because solutions are collective!

« Four degrees Celsius between you and me » Exhibition

À l’école nationale supérieure d’architecture, 5 avenue de Sceaux, 78000 Versailles / Free admission
Tuesday to Friday: 12pm to 7pm and weekends: 11am to 7pm

Scientific studies show that temperatures in France will rise by +4°C by 2100.

Its current temperate climate will be transformed into a subtropical one. The exhibition will look further south, to these already warmer climates, to find models for building architecture in France today that can withstand this rising heat.

4 degrees Celcius between you and me”: By 2100, the Paris Region could be experiencing a climate similar to that of southern Spain, Mexico or Japan. A rise of +4°C will transform our ecosystems, moving plants and animals northwards at a rate of more than one meter per hour. Cities will have to adapt to summer temperatures flirting with 50°C, prolonged droughts and tropical rains.

Through this exhibition, we invite you to explore vernacular solutions from warmer latitudes, to discover contemporary practices that are already responding, and imagine the future of towns and cities in the Paris Region adapted to this new climate. Together, let's think about architecture and urban spaces that can preserve life in all its forms in the face of these challenges.

The Potager du Roi, a laboratory for future landscapes

We invite you to visit the "Nous... le climat" exhibition, located in the Potager du Roi (Kitchen Garden of the King) in Versailles. Designed by Agence TER, with Henri Bava, Michel Hössler, and Olivier Philippe, this interactive scenography aims to engage visitors into understanding the challenges of climate change. At the heart of the garden, a monumental 300-meter-long table symbolizes conviviality and conversations. It invites visitors to take a seat, share their experiences, engage in dialogue, and learn more about the landscape professions. Conferences, workshops, and festive events enliven this open-air exhibition, where everyone can act against climate change. We look forward to your participation in this unique journey towards a sustainable future.

The exhibition "Nous... le climat" (“We... the climate”) explores how landscape professions play a key role in the face of climate challenges. These skills empower us to rethink our relationship with the environment and envision pragmatic solutions. This exhibition, curated for BAP 2025, is located in the Potager du Roi at Versailles (Kitchen Garden of the King), a renowned landscape education institution. It invites us to collectively feel, understand, and act for a sustainable future.

« Changer les Climats » Exhibition

Au musée Lambinet, 54 boulevard de la Reine, 78000 Versailles / Free admission
Wednesday to Friday: 12pm to 7pm and weekends: 10am to 7pm

The “ Changer les Climats ” exhibition explores how built environments can be transformed into urban ecology. Producing an improved microclimate, each of these ecologies has the potential to increase the resilience of the urban condition in the face of the challenges of the climate crisis.

This exhibition of projects and research by Bas Smets shows how new urban ecology can be conceived and constructed.

A selection of three major projects from Smets’s international practice demonstrates how landscape architecture can answer different challenges of the climate crises: from enhancing outdoor comfort and reducing the perceived temperature around Notre-Dame in Paris, to the transformation of a sterile wasteland in Arles into a self-sustaining ecology, to the creation of an embankment park that mitigates the rise of water levels in Antwerp.

At a time of climate change and the quest for thermal comfort, it is essential to show examples of practical projects that explore these ideas of climatic comfort and greening. The city offers opportunities to rethink the built environment as an urban ecology that produces climates.

What these projects hold in common is a commitment to solution-based design grounded in scientific research. Three projects respond to three different climate challenges: rising sea levels, global warming and the transformation of polluted and sterile soils into a fertile ecosystem.

Maintained and reproduced carefully, these ecologies can be resources for a sustainable future.

A dreamlike immersion in the nocturnal life of regional nature reserves

When daylight fades and humans retreat, a mysterious dance takes place in the heart of Île-de-France's natural areas. In these shelters, surrounded by urbanization, wildlife is secretly active. Unexpected silhouettes stand out in the headlights; phantasmal shadows appear, feeding, drinking or hunting in the moonlight. In the morning, only a few discreet traces bear witness to their stealth passage.

This open-air exhibition presents some fifteen photographs captured on the spot by photographer Nicolas Davy. In the chiaroscuro of twilight, it captures a dreamlike interlude where nature converses with the silence of the city...

Our cities are home to unsuspected and fascinating wildlife. Originally from Paris, I discovered photography by exploring my immediate environment and naturally gravitating towards urban wildlife

For the last fifteen years, I've been travelling around the Paris region to capture this discreet wildlife, nestling in the last interstices of our towns and cities that are still free or fallow. My aim is simple: to show that nature on the outskirts of cities is wonderful and far from ordinary, and to reconnect city-dwellers with the nature that surrounds them.

In producing this exhibition, I've made a point of respecting the ecosystems photographed, capturing authentic moments at dawn or dusk, using minimalist equipment and no artifice. I hope that these images will encourage people to rediscover the precious link between the urban environment and living things.

20 years of urban transformation

From the renovation of the former Royal Hospital and the emergence of the Gally and Satory districts, to the construction of facilities in the Chantiers station area, the Tourist Office and the Biosphere, Versailles has been transforming itself over the last ten years. Architects, town planners and landscapers, commissioned by the city authorities, took up projects that have slowly but surely transformed, embellished and greened the public space and changed our lifestyle.

A series of photos, films and models, providing a visual prism of Versailles “before-and-after”, reveal our numerous past, present and future achievements whose design is respectful of the architectural, urban and plant environment of the Royal City.

Exhibition supported by la ville de Versailles

Images often speak louder than words.

Whether they picture a public square made pedestrian-friendly, a renovated historic building or an urban wasteland transformed into a green landscaped area, the photos comparing the Versailles of before and after each tell a story. These changes, sometimes subtle and sometimes spectacular, involve not only aesthetic changes but also functional and environmental improvements that meet the needs of our constantly developing city.

The “Versailles before-and-after” exhibition, which showcases these many changes, leads us to wonder how they are transforming our everyday lives and the way we live in the city. And, above all, was it better before?

« Petite Agora de la Métropole du Grand Paris » Pavilion

Opposite the Château, avenue de Paris, 78000 Versailles / Free admission
Tuesday to Friday: 12pm to 7pm and weekends: 11am to 7pm

A place to meet and debate in the heart of the city

Positioned in a key location, facing the Chateau de Versailles and along the historic axis of Avenue de Paris, the Petite Agora of the Greater Paris Metropolis offers a unique space for discussion and debate on architecture, cities, and climate during the biennale.

To highlight the challenges faced by cities in the context of climate change, the Greater Paris Metropolis has made the bold choice for BAP! 2025 to construct a solid timber structure using simple, efficient, and sustainable building techniques that minimizes the use of steel and eliminates concrete. Designed by Jean-Christophe Quinton, the Petite Agora of the Greater Paris Metropolis demonstrates that it is possible to create highly functional, aesthetically refined buildings while maintaining the lowest possible carbon footprint.

Pavilion supported by la Métropole du Grand Paris

The Petite Agora is located on the iconic Avenue de Paris in Versailles, directly facing the Château. The expressiveness of its form stems from its two large, distinctive windows, each closely connected to its surroundings: first, a horizontal opening frame the Château, while the second, a vertical one, frames the tree-lined pathway along the former stables. Between the two, the exposed solid timber framework creates a gentle slope that houses a 150-seat performance hall. Designed as a space for gathering and discussions at the heart of the city, the Petite Agora hosts a wide range of cultural events, including concerts, theatre performances, and conferences. It offers visitors a contrasting spatial experience, simultaneously perceived both vertically and horizontally. The structure creates a warm and welcoming atmosphere, thanks to a framework made of nailed laminated timber beams. These beams represent an ecological, technical, and economic innovation, shaping a strong architectural identity intended to be shared by all.
