Église Saint-Ambroise
The Saint-Ambroise church was built in the eclectic style between 1863 and 1868 on a former chapel dating from 1659. The chapel was destroyed during the construction of the Boulevard du Prince Eugène, renamed Boulevard Voltaire in 1870. During the Commune in 1871, without preventing worship, the church was the headquarters of the Ambroise club, known as the proletarians' club, which included feminist speakers. This club published the newspaper "Le prolétaire".
