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.
