One of Paris’s listed pools, the Butte-aux-Cailles swimming pool has been a pioneer of public bathing since 1922, when it was built by architect Louis Bonnier. Its red brick façade nods to Art Nouveau style, while inside, the vaulted ceiling and grand arches give it an almost church-like feel. Best of all, the water is naturally warm, sourced from deep artesian wells. Renovated in the early 2010s, this gleaming pool features a 33-metre indoor pool and a 25-metre outdoor pool that’s open year-round and feels like a dip out of time. The outdoor area also includes a paddling pool and a solarium. Now then, get swimming.
