Tuileries (twēˈlərēz, Fr. twēlrēˈ) [key], former palace in Paris. Planned by Catherine de' Medici and begun in 1564 by Philibert Delorme, it occupied part of the present Tuileries gardens. It was rarely used as a royal residence until 1789, when Louis XVI was forced by the revolutionists to move there from Versailles. He and his family were brought back there after their attempted flight (1792) and their arrest at Varennes. A few weeks later (Aug. 10, 1792) a mob attacked the palace (see French Revolution). Napoleon I made the Tuileries his chief residence, as did Louis XVIII, Charles X, Louis Philippe, and Napoleon III. During the Commune of Paris of 1871, the palace was destroyed by fire. The spendid formal gardens, laid out by Le Nôtre, remain and are connected to the Louvre museum.
