Bains Lillois, Public bath in Lille, France.

The Bains Lillois is a bath house in Lille featuring a neoclassical facade supported by four columns of pink marble and topped with a frieze crowned by a balustrade balcony. The original building contained 270 cabins and three separate swimming pools designed for different skill levels.

Built from 1890 on plans by architect Albert Baert, the Bains Lillois opened as a social and hygienist bathhouse with one of France's first heated swimming pools. The pool closed in 1991 for failing safety standards and never reopened. The building was demolished in 1998, leaving only the facade, which was fully restored in 2009.

Léon Verdonck, the director of the Bains Lillois, founded two of France's first competitive swimming societies and introduced water polo to the country. In 1898 only three societies practised competitive swimming: the Tritons lillois, the Pupilles de Neptune de Lille — the oldest water polo club in France — and the Libellule de Paris.

The bath house closed in 1991 for failing safety standards and was demolished in 1998; only the facade remains, restored in 2009. It stands at 219 ter, boulevard de la Liberté, near the République - Beaux-Arts and Lille Grand Palais metro stations. The street-level access is protected by glass bays.

In 1924, artist Alfred Labille created specialized stained glass windows for the bath house, bringing artistic elements into this public facility. These artistic details show how beauty and design were valued even in everyday functional spaces.
