圆明园
The Old Summer Palace was set aflame by 3,500 British troops and burned for three days. Lord Elgin and his troops looted many treasures from the palace and took them to Britain. Attacks on the nearby Summer Palace (Qingyi Yuan) were also made, but the extent of destruction was not as great as to the Old Summer Palace. On 24 October 1860, Lord Elgin signed the Convention of Peking, which stipulated that China was to cede part of Kowloon Peninsula and Hong Kong in perpetuity to Britain.
