The Pavillon de l’Horloge (French, "Clock Pavilion"), also known as the Pavillon Sully, is a prominent pavilion located in the center of the west wing of the Cour Carrée (Square Court) of the Palais du Louvre in Paris. The two names Pavillon de l'Horloge and Pavillon Sully are now often reserved for the central pavilion's eastern and western faces, respectively.
The pavilion was built just north of the older Lescot Wing between 1624 and about 1645. The famous structure, with its square-domed roof, was designed by architect Jacques Lemercier (1585–1654). The name comes from a clock (French: horloge) later incorporated into its elevation.
The structure become known as the Pavillon Sully (after Maximilien de Béthune, duc de Sully) early in the 19th century. Its western facade was completely remodeled by Hector Lefuel in the 1850s during the Second Empire.
