The Church of Saint-Sulpice is a Roman Catholic church in Paris, France, on the east side of Place Saint-Sulpice, in the Latin Quarter of the 6th arrondissement of Paris, France. It is only slightly smaller than Notre-Dame and thus the second largest church in the city. It is dedicated to Sulpitius the Pious. Construction of the present building, the second church on the site, began in 1646. The new building was founded in 1646 by parish priest Jean-Jacques Olie. Construction began in 1646 to designs which had been created in 1636 by Christophe Gamard, but the Fronde interfered, and only the Lady Chapel had been built by 1660, when Daniel Gittard provided a new general Baroque design for most of the church.
