"The Jewish community was dissolved in 1940 by the German occupiers, and the synagogue was ransacked during WW2. After the war, ownership reverted to the Jewish Consistoire, which ceded it to the municipality in 1954. It was used as a warehouse and from 1984 as a fire station. According to France’s Heritage Foundation, which was a partner with the city in the restoration project, work included refurbishment of massive stone elements, the restructuring of the interior of the ground floor and the removal of “interventions that had damaged the integrity of the building.""
