Invaders burned Yuanmingyuan twice in history. The Yuanmingyuan was burned down for the first time in the tenth year of Xianfeng in Qing Dynasty (1860), and the British and French allied forces invaded Beijing. British and French allied forces burned and looted everywhere, savagely plundered and burned the world-famous Yuanmingyuan, and most of the temple buildings in the park were destroyed by fire. The British and French allied forces burned the Yuanmingyuan, aiming to raze it to the ground. However, due to the large area of Yuanmingyuan, scattered scenic spots and vast waters, some remote places and scenic spots in the water survived. According to the winter survey in the 12th year of Tongzhi (1873), there are still 13 buildings in the park. For example, Pengdao Yaotai and Cangzhou Wu in Yuanmingyuan, Dagongmen and Zhengjue Temple in Qichun Garden, etc. The Yuanmingyuan was burned down for the second time in the 26th year of Guangxu reign of Qing Dynasty (1900). Eight-Nation Alliance invaded Beijing and set fire to Yuanmingyuan again, so that the only remaining 13 royal palace buildings here were looted and burned again.
