City hall of Cachan, Historical town hall in Cachan, France.

The City Hall of Cachan is a 1930s municipal building constructed with reinforced concrete and faced with yellow bricks, featuring a prominent bell tower at its center. The structure sits near Raspail Park at 8 rue Camille-Desmoulins and houses the town's administrative offices.

Cachan split from Arcueil in 1923, and mayor Léon Eyrolles decided to build a separate town hall while the town used temporary premises. Architects René Chaussat, Jean-Baptiste Mathon and Joannès Chollet designed the building, which was inaugurated in 1935 by foreign minister Pierre Laval.

The building's name and role date from Cachan's split from Arcueil in 1923, when mayor Léon Eyrolles pushed for an independent town hall. It was inaugurated in 1935 by Pierre Laval, then foreign minister. Visitors can still see the ceremonial rooms protected since 2002: the vestibule des pas perdus, the grand staircase, the salle des fêtes et des mariages and the council chamber.

The building functions primarily as a municipal office, so interior access may be limited, but the exterior with its bell tower is visible from the street. Raspail Park nearby provides a good spot to view the structure and take a break.

The 11 March 2002 listing covers more than the facades: it also protects the adjoining square, the ground of the plot, the vestibule of the pas perdus, the grand staircase, the function and wedding room and the council chamber. The architects were René Chaussat, Jean-Baptiste Mathon and Joannès Chollet.
