Saint Peter's Church in the Montrouge quarter in the 14th arrondissement of Paris was built during the great reconstruction of the capital in the 1860s. It is a neo-Renaissance building with a tall, rectangular tower-belfry. The interior, divided by columned arcades, is unadorned. They are covered with a wooden ceiling.
The church was designed by Emilie Vaudremer, an architect working on the extension of the 14th district. The church was built of stone and concrete. It has a basilica layout with a massive transept. Above the building there is a high tower with a clock and a quadruple neo-Romanesque window.
The interior is very austere, devoid of paintings and decorations. They are covered with a wooden roof truss with visible joists and rafters. In the altar there is a modern triptych with the figure of the Virgin Mary with Child in the central part.
