Built at the end of the 16C, the neo-Baroque façade was added in 1870 by architect Sainte-Marie Perrin. The dome has eight large windows and its covering supports the lead globe and cross, symbols of the Carthusians. Inside, the nave is the result of a campaign of works undertaken by architect Delamonce in the 18C. At the transept crossing is the baldaquin (1738), whose four columns support the crown, from which drapes tumble abundantly. A true gem of Baroque style.
