The Louvre Castle was originally built by Philippe II of France beginning in 1190 to house the King's archives and treasures, and given machicoulis and features of a Gothic fortress. However, it was soon made obsolete by the development of artillery, and in the 15th century it was remodelled into a comfortable residential palace. While the outer walls retained their original military appearance, the castle itself, with a profusion of spires, towers, pinnacles, arches and gables, became a visible symbol of royalty and aristocracy. The style was copied in chateaux and other aristocratic residences across France and other parts of Europe.
