The Neoclassical facade of the huge Eglise St-Sulpice dominates the enormous square of the same name; it is in some sense at the center of the Left Bank. Church dedicated to Saint Sulpicius, a 6th century bishop of Bourges. The foundation of the church Saint-Sulpice, one of vastest and richest of Paris, goes up at least in the 12th C. The grandiose Italianate façade with double colonnade is by Jean-Baptiste Servandoni, a Florentine architect, from 1733-45, although two towers remained unfinished at his death. The one on the right has never been completed and still 5m short of its neighbor. The church is noted for its frescoes by the 19th -century genius of Romantic painting, Eugène Delacroix (whose Rue Furstenberg studio is not far off) in the first chapel on the right of the entrance, depicting "Jacob’s Fight with the Angel", "Heliodorus Chased out of the Temple" and "St. Michael Killing the Dragon" (turn on the light in the chapel if you visit the church late afternoon). Another priceless treasure is Servandoni’s rococo Chapelle de la Madonna with Pigalle statue of the Virgin, and famous organ of 1781. If you like this kind of classical music - Prelude for Grand Mass on Sundays begins at 10:15am. The Organ Recital (Audition) begins at approximately 11:30am and lasts 30 minutes (followed by the 12:05 Mass, including the Offertory, Communion, and a Postlude).
A copper line in the middle of the choir symbolizes the zero meridian of Paris. In the transept, the inlaid copper band runs along the floor from north to south, connecting a plaque in the south to an obelisk in the north. A ray of sunshine passes through a hole in the upper window of the south transept during the winter solstice, striking marked points on the obelisk at mid-day. A beam of sunlight falls on the copper plaque during the summer solstice and behind the communion table during the spring and autumn equinoxes.
Servandini had also projected construction in front of the church, of a harmonious place and monumental broadside of beautiful houses, of which only one was built, to the angle of the street of the Quills. Work was modified thereafter by Chalgrin. The fountain of the Four-Bishops (Bossuet, Fénelon, Massillon, and Flechier from the Luis XIV era) in the center of the place, was built by Visconti in 1847. Fontaine des Quatre-Points Cardinaux (also known as Quatre-Évêques) – a name is a pun on the compass points and four clerics who did not become cardinal.
