Piscine Molitor (French pronunciation: [pisin molitɔʁ]; also known as the Piscines Auteuil-Molitor or the Grands établissements balnéaires d'Auteuil) is a swimming pool and hotel complex located in Porte Molitor, 16th arrondissement of Paris, Île-de-France, Paris, France. It is next to the park Bois de Boulogne, and between Stade Roland Garros and Parc des Princes. The complex was built in 1929 and inaugurated by Olympic swimmers Aileen Riggin and Johnny Weissmuller. The pool is known for its Art Deco designs and the popular introduction of the bikini by Louis Réard on 5 July 1946. The pool was classified as a French monument historique on 27 March 1990, after having fallen into disuse and closing in 1989.[2]
