Right in the heart of the Latin Quarter, just steps from boulevard Saint-Germain, this is a beautiful art deco pool with two mezzanine levels. Constructed in 1934 by the architect Lucien Pollet (also behind the famous, now disused Piscine Molitor, plus Jonquière and Pailleron), it's famous for featuring in Krzysztof Kieslowski’s film ‘Trois Couleurs: Bleu’.
Registered as a historical monument since 1981, the site features individual changing cabins installed on two walkways bordered by metal railings, a huge glass ceiling and mosaic frescoes: without doubt one of the most beautiful pools in the capital (with entry fee to match). It can get a little crowded given that there is only one pool (the old-fashioned 33-metre style), but by paying a few euros more, you can use the sauna, squash court, cardio room and fitness courses. Open until midnight on weekdays.
