Blazon sculptured in pediment of the swimming pool of Butte-aux-Cailles one of the most old swimming pools of Paris.
Fed by an artésien well conceived by François Arago, giving access to a water in 28 °C since 1893, the swimming pool was conceived by the architect Louis Bonnier and built between 1922 and 1924 in addition of ancient public baths dating 1908. The sanitary considerations and of hygiene, news in this time, were taken into account, with for example the passage obliged by the bathers by showers and pédiluve. The facade of the swimming pool is in red bricks, unusual material in Paris for this type of établisement, in a style Art nouveau.
It is registered in conformance with ancient memorials since an order of July 31st, 1990.
