The museum is housed in the Louvre Palace (Palais du Louvre), originally built as a fortress in the late 12th century under Philip II. Remnants of the fortress are visible in the basement of the museum. The building was extended many times to form the present Louvre Palace. In 1682, Louis XIV chose the Palace of Versailles for his household, leaving the Louvre primarily as a place to display the royal collection, including, from 1692, a collection of ancient Greek and Roman sculpture.[7] In 1692, the building was occupied by the Académie des Inscriptions et Belles Lettres and the Académie Royale de Peinture et de Sculpture, which in 1699 held the first of a series of salons. The Académie remained at the Louvre for 100 years.[8] During the French Revolution, the National Assembly decreed that the Louvre should be used as a museum to display the nation's masterpieces.
