Meudon National Estate
Laying Marble
### Commissariat Manuel Neves
In September 2026, the Orangerie in Meudon will host Extending the Marble, an unprecedented solo show by Franco-Brazilian artist Jaildo Marinho, bringing together a body of works specially conceived for this remarkable venue.
Jaildo Marinho has had his studio in Meudon for over 20 years and has shown his work internationally. Influenced by Brazilian neo-concretism and the Madí movement — two avant-garde currents where audience participation was essential — Marinho has spent decades developing a visual research in which geometric forms and classical materials serve as vehicles for narratives rooted in the culture of Brazil’s Northeast, the region of his childhood. In his new sculptures, the artist resonates with the world of laundry workers.
Extending the Marble: when stone becomes fabric
Created specifically for this exhibition, the marble works are traversed by monumental folds. At first glance, one might mistake them for suspended fabrics; in fact, they are marble, with the stone’s natural veins and Marinho’s refined carving responding to one another.
Through this unprecedented series, the artist continues his meditation on essential forms and on the material’s capacity to transcend its own nature.
Meudon, a memory of the laundry
The exhibition finds a particular resonance in Meudon. In the 19th and early 20th centuries, the town was a major center of laundry activity in the Paris region. Generations of washerwomen washed, whitened and dried linens destined for the capital and its nearby suburbs.
Marinho’s sculpted folds evoke, in a poetic and contemporary voice, this local memory. Between the weight of marble and the lightness of stretched fabric, the show forges an unexpected dialogue between social history and artistic creation.
An exceptional heritage setting
Nestled in the heart of the Meudon National Domain, the Orangerie provides a striking frame for this presentation. Still active today, it houses in winter the orange trees from the Tuileries, Saint-Cloud and Meudon. In warm months, its brick architecture and its impressive volume offer an ideal setting for these monumental works.
The meeting of the place’s nobility with that of marble helps make Extending the Marble a singular experience, where space, light and matter engage in intense dialogue.
Exhibition from September 3 to 27, 2026

The Astonishing Saga of the Meudon Viaduct
### Commissariat Jean Ménard
Discover the astonishing story of the Meudon Viaduct!
For nearly two centuries, the Meudon Viaduct, also known as the Hélène Bridge, has spanned the Arthelon Valley. A keystone of the city’s heritage, it has left a lasting mark on landscapes and imaginations alike.
The first part of this exhibition traces the viaduct’s construction from 1837 to 1840 by engineers Payen and Perdonnet. A feat of technical prowess and human endeavour, the structure came to life in the era of the first railways.
Built on unstable ground, the viaduct demanded the full ingenuity of its designers and the labor of a multitude of workers. Open to traffic in September 1840, it underwent modernization in the 1930s under Raoul Dautry, including doubling the tracks and electrification. Architect Urbain Cassan reinforced the structure while preserving its original appearance and elegance.
The second part of the exhibition offers another perspective: that of artists. Between 1850 and 1930, as Paris stood at the heart of the avant-garde, the Meudon Viaduct appeared in numerous works, sometimes as ornament, sometimes as a symbol of modernity and a dialogue between nature, city and industry. A few paintings from the Courtois Collection complete the monument’s portrait.

Huvé's Folly
Self-guided tour of the Folie Huvé gardens
The "Folie Huvé", listed as a historic site in 1945, sits tucked away in a neighborhood undergoing rapid transformation.

If weather permits, information panels about the site will be installed in the garden.

Bellevue Pavilion
CNRS and the Pavillon Bellevue, from yesterday to today
Come and discover the exhibition The CNRS and the Bellevue Pavilion, from yesterday to today. Through a wealth of photographs drawn from glass plates and film stock dating back to 1919, preserved and highlighted by CNRS Images, this exhibition traces the history of this Meudon heritage.
Today, the Bellevue Pavilion hosts one of CNRS’s delegations, but more than that, it has stood as the organization’s historic headquarters since its founding in 1939.
Before that, this Belle Époque building served a variety of roles: a luxury hotel in the 19th century, the dance school of the famed Isadora Duncan, and a military hospital during World War I. Its scientific journey truly began in 1919 when it housed the Office des inventions, which became the National Office for Scientific, Industrial and Inventions Research (ONRSII) in 1922, and finally the CNRS, from 1939 to the present.
Participation conditions: Free / Open-access exhibition within the site's capacity - Free | No reservations
Hours: Saturday, September 19, 2026 — 11:00 to 17:00
Quintessence Residence
Two warm outdoor works by Guillaume Bottazzi
These works were created by the artist in 2023. Sunny, sensorial and poetic, they transport viewers into a sun-drenched, invigorating imaginative world.
They are located outside the entrance to a residence and each stands 1 meter 65 tall.
They are made of enamels laid over tempered and laminated glass.
The reflective nature of the material draws the viewer in. This on-site commission calls for a holistic approach that integrates place-specific parameters—while bringing cheer to a cluster of white, vegetated buildings.
On the occasion of the 43rd edition of European Heritage Days, painter-artist Guillaume Bottazzi, a pioneer of applied neuroaesthetics, invites us on a gargantuan artistic journey comprising more than 90 heritage artworks that do us good.
These works are to be discovered across France—from Hauts-de-France to Occitanie, including the capital, Greater Paris, and the regions Auvergne-Rhône-Alpes and Provence-Alpes-Côte d’Azur.
Guillaume Bottazzi has signed more than 180 heritage-oriented works aimed at valorizing heritage, across Europe, the United States, China and Japan, commissioned by cities, museums and architects. They fit into the architectural heritage of the places where they are located.
This initiative comes as the European Union and France have designated mental health as the “Great National Cause” for 2026. These site-specific works improve our quality of life. These poetic creations, grounded in insights from neurobiology, forge an ecosystem that helps people live more happily.
The public is invited to stroll while looking at these works to see whether they receive a dose of well-being.
