Although still used for coronation ceremonies, the Kremlin was abandoned and neglected until 1773, when Catherine the Great engaged Vasili Bazhenov to build her new residence there. Bazhenov produced a bombastic Neoclassical design on a heroic scale, which involved the demolition of several churches and palaces, as well as a portion of the Kremlin wall. After the preparations were over, construction was delayed due to lack of funds. Several years later the architect Matvey Kazakov supervised the reconstruction of the dismantled sections of the wall and of some structures of the Chudov Monastery, and built the spacious and luxurious Offices of the Senate, since adapted for use as the principal workplace of the President of Russia. 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. 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. Explosions continued for three days, from 21 to 23 October 1812. However, rain damaged the fuses, and the damage was less severe than intended. Restoration works were undertaken in 1816–1819, supervised by Osip Bove. During the remainder of the reign of Alexander I, several ancient structures were renovated in a fanciful neo-Gothic style, but many others, including all the buildings of the Trinity metochion, were condemned as "disused" or "dilapidated" and were torn down.
