The Fountain Saint-Sulpice (French: Fontaine Saint-Sulpice) or Fountain of the Four Bishops (Fontaine des Quatre Evêques), built in the center of the square between 1844 and 1848, was designed by the architect Joachim Visconti. The fountain presents the statues of four bishops, one on each of its sides:
Some people call this monumental fountain the fontaine des quatre points cardinaux (lit. the "Fountain of the Four Cardinal Directions", which is pronounced as the "Fountain of the Four Not Cardinals"). This is a bit of innocent wordplay; none of the four esteemed bishops ever became a cardinal.
