The Château Landon Pool, Paris’s oldest swimming facility, opens its doors once again.

Closed since 2018, the Château-Landon swimming pool in the 10th arrondissement of Paris is finally reopening its doors this Monday, February 23, 2026. Originally opened in 1884, this historic swimming pool has undergone a €14 million renovation. Here’s everything you need to know about the new features, pricing, and opening hours.

Highly anticipated by nostalgia seekers, the Château-Landon swimming pool is finally reopening on Monday, February 23, 2026, at 9 a.m. Located on Château-Landon Street in the 10th arrondissement, this beloved Parisian spot has been eagerly awaited for over seven years. Since its forced closure in autumn 2018, this piece of 19th-century Paris had fallen silent behind its closed doors, awaiting a major renovation project carried out at a staggering €14 million. Nestled between Gare du Nord and the Canal Saint-Martin, the first indoor swimming pool in France is set to welcome visitors once again.

Why Did Château-Landon Pool Have to Close?

The story could have taken a very different turn. In 2018, an incident on the vault of the swimming pool forced the City of Paris to close the facility overnight. A tough blow for local residents in the 10th arrondissement, who are very attached to this unique place. Opened in 1884 and designed by architect Lucien-Dieudonné Bessières, the Château-Landon swimming pool stands as a rare testament to 19th-century seaside architecture. It almost changed its appearance once before, in 1925, when railway expansion works at the Gare de l’Est compelled the city to reduce its pool from 42 to 25 meters. It was during this renovation that the pool adopted its iconic "ocean liner" look, with two levels of deck cabins that give it the appearance of an aquatic theater.

What really changed after the renovations?

After several years of planning and study, the project was awarded to Bouygues Building Île-de-France and officially launched in the summer of 2024. The construction is slated to take 18 months, with up to 50 workers on-site daily. The clear goal: to restore the pool without compromising its original charm. The 25-meter pool has been preserved, but it now features a new stainless steel tank that’s far more durable than the old mosaics. The vaulted ceiling has been completely rebuilt using polycarbonate and steel panel roofing to create a genuine "thermal cushion." The facades have been insulated, the water treatment upgraded with active charcoal filters, and the lighting fully revamped. The result? 40% reduction in overall energy consumption, a 54% decrease in hot water heating costs, and a 25% savings on lighting. And for those feeling nostalgic, the original colors—blue, red, and yellow—are making a vibrant comeback on the walls.

What activities are planned for the reopening?

This also marks the beginning of a new, more diverse offering. Beyond the traditional swimming sessions, the pool now offers baby swimming lessons, dedicated prenatal classes for pregnant women, sports health programs, and tailored sessions for people with disabilities. The opening hours have been expanded: the pool is open on Mondays from 9 AM to 10:30 PM, Tuesdays from 9 AM to 8:30 PM, and Wednesdays from 7 AM to 10:30 PM. The ground floor is now completely accessible to individuals with reduced mobility, and two family cabins have been added for visitors coming with loved ones.

Will the Prices Rise?

No, and that’s good news. The prices remain in line with those of Parisian municipal pools: general admission costs €3.50, or €2 for reduced fare. Regular visitors can purchase a 10-entry card for €28 (€16 reduced), and a three-month membership is available for €43 (€22 reduced). Swimming lessons start at just €15 for 30 minutes, catering for groups of 1 to 3 people, or €66 for a package of six sessions. There was some controversy last year when the 10th arrondissement announced it would outsource management to a private company through a public contract: unions decried privatization. However, Mayor Alexandra Cordebard has assured that no public employee positions will be cut, and there will be no changes for users in terms of prices or public service commitments.

So, let's go without hesitation. The Château-Landon swimming pool remains one of the most unique spots in Paris for swimming, and catching sight of this fountain after seven years feels genuinely touching. Head over to 31, rue du Château-Landon, easily accessible from the Louis Blanc (lines 7 and 7bis) and La Chapelle (line 2) metro stations. The full schedule and online ticketing are available on the City of Paris website.
