Louvre [SEP] Introduction
The Académie remained at the Louvre for 100 years. During the French Revolution, the National Assembly decreed that the Louvre should be used as a museum to display the nation's masterpieces. The museum opened on 10 August 1793 with an exhibition of 537 paintings, the majority of the works being royal and confiscated church property. Because of structural problems with the building, the museum was closed in 1796 until 1801. The collection was increased under Napoleon and the museum was renamed "Musée Napoléon", but after Napoleon's abdication, many works seized by his armies were returned to their original owners. The collection was further increased during the reigns of Louis XVIII and Charles X, and during the Second French Empire the museum gained 20,000 pieces.
