The Pavillon de l’Horloge (French, "Clock Pavilion") is a prominent element of the Palais du Louvre in Paris. It was built between 1624 and 1654 under King Louis XIV. The famous structure, with its distinctive domed roof, was designed by architect Jacques Lemercier (1585–1654). It is adjacent to the famous Lescot Wing. Its older name comes from a clock later incorporated into its elevation. More recently, it has also become known as Pavillon Sully (after Maximilien de Béthune, duc de Sully).
