Le Beffroi, Convention center in Montrouge, France.

Le Beffroi is a convention center in Montrouge with performance halls, exhibition areas, reception spaces, and meeting rooms spread across multiple floors. The facility includes a foyer-bar, two winter gardens, and offers various rooms designed for different types of gatherings.

In 1932 mayor Émile Cresp commissioned architect Henri Decaux to build a municipal administrative centre, opened in 1933 in Art Deco style. In 2006 it became the town theatre when a new administrative centre opened nearby. Renovated from 2009 to 2012, it reopened in May 2012 as a cultural and congress centre; the building is listed in the general inventory of cultural heritage.

The building hosts two performance halls and exhibition spaces that shape artistic life throughout the year. These rooms serve the local community as a gathering place for theater, shows, and cultural meetings.

The venue provides professional equipment such as digital podiums, projectors, and sound systems throughout all spaces. Free WiFi is available everywhere, making it easy to stay connected while using the different areas.

The carillon installed in January 2000 has 27 bronze bells engraved with the names of Montrouge's mayors; three bells added in January 2016 bear the names of three benefactors. The 43-metre belfry can be climbed by a staircase of 193 steps, mainly during heritage days, for a panoramic view over Montrouge and Paris.
