The building was constructed in 1876 with assistance by the internationally known Gustave Eiffel. Inside, the nave is 21 meters high (69 feet), and the elaborate façade features depictions of the Tablets of the Law and the heraldic shield of Paris. The synagogue is a member of the ACIP (Consistoire de Paris).
