It's a first in 150 years: the Buttes-Chaumont park, a gem in the 19th arrondissement and a favorite spot for Parisians seeking green spaces, is getting a monumental renovation. The goal? To secure its cliffs and walkways, revive areas that have been closed for years, boost biodiversity, and prepare for the warming climate. And to envision this centennial future, the City of Paris is launching a big consultation open to everyone.

With its Temple of the Sibyl perched at the top of the island, dizzying cliffs, waterfalls, and meadows that welcome picnics, joggers, and lovers, the Buttes-Chaumont Park has been one of the most spectacular backdrops of the capital since 1867. However, as it is built on former gypsum quarries, the park has always required massive work to stay standing. Today, nearly 5% of its area is off-limits, a figure that highlights the necessity for quick intervention to prevent landslides, cracks, and ground slips.

A "construction of the century" estimated at 85 million euros

During a public meeting held at the town hall of the 19th arrondissement in September, the City unveiled more details about the scale of this rehabilitation. The project, described as the “construction of the century” by Mayor François Dagnaud, is estimated at 85 million euros and ...

should kick off at the end of 2027, after a long study phase planned for 2026. The goal is to secure the cliffs sustainably and restore the waterfalls, all while preserving the site's biodiversity. To support this extraordinary process, a committee of independent experts has been commissioned to ensure that the park retains its original identity, envisioned over 150 years ago.

Safety, Climate, and Biodiversity at the Heart of the Project

The goal is clear: to make the park safer, more welcoming, and more resilient. The cliffs, walkways, cave, and banks will be reinforced to prevent any risk of collapse. The island and its famous Path of the Aiguilles, currently inaccessible, will finally be reopened to the public. Water management will be rethought to protect the fragile soil and avoid infiltration that damages the gypsum. And because the Buttes are also a reservoir of biodiversity, the project aims to preserve the wildlife and plants, remove invasive species, and enhance the greenery. The idea is to restore the original spirit of the park, inspired by the Normandy cliffs and alpine meadows, while preparing it for the climate challenges of the decades to come.

An Open Consultation for Parisians

For this

The extraordinary renovation, the City of Paris and the 19th arrondissement want to involve the residents. Public meetings, exhibitions, exploratory walks, and online contributions will highlight the upcoming months to gather the ideas and wishes of everyone who strolls through the Buttes on a daily basis. Far from a project carried out behind closed doors, this initiative is therefore being developed hand in hand with the locals and users.

A park ready for the next century

The Buttes-Chaumont park, classified as a natural monument since 1958, is not meant to be transformed into a sterile space. Quite the opposite! It’s about reaffirming its identity, restoring its picturesque character, and making it an even more pleasant place to enjoy, both day and night.

To participate in the consultation: head over here between September 22 and October 20, 2025.
