During the Imperial period, from the early 18th and until the late 19th century, the Kremlin walls were traditionally painted white, in accordance with fashion.[9] French forces occupied the Kremlin from 2 September to 11 October 1812, following the French invasion of Russia. When Napoleon retreated from Moscow, he ordered the whole Kremlin to be blown up. The Kremlin Arsenal, several portions of the Kremlin Wall and several wall towers were destroyed by explosions and the Faceted Chamber and other churches were damaged by fire.
