In 1860, during the Second Opium War, the British and French expeditionary forces looted the Old Summer Palace. Then on October 18, 1860, in order to "punish" the imperial court, which had refused to allow Western embassies inside Beijing, the British general Lord Elgin- with protestations from the French - purposely ordered the torching of this massive complex which burned to the ground. It took 3500 British troops to set the entire place ablaze and took three whole days to burn. The burning of the Gardens of Perfect Brightness is still a very sensitive issue in China today.
