this "european style" pavilion is in the ruins of the old summer palace. it still stands as a monument to the brainless idiocy of the drug peddling murderers who destroyed the palace and as a stern warning to sovereign nations of the seriousness of preparedness for national defense. it was spared as it was surrounded by a stone wall maze that proved insurmountable to the attackers. From wikipedia: 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 to set fire to the huge complex which burned to the ground. It took 3,500 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.
The Imperial Gardens were made up of three gardens: the Garden of Perfect Brightness proper, the Garden of Eternal Spring (Chinese: 長春園; pinyin: Chángchūn Yuán), and the Elegant Spring Garden (Chinese: 綺春園; pinyin: Qǐchūn Yuán); they covered a huge area of 3.5 km² (865 acres). They were almost 5 times the size of the Forbidden City, and 8 times the size of the Vatican City. They had hundreds of halls, pavilions, temples, galleries, gardens, lakes, etc. Several famous landscapes of southern China had been reproduced in the Imperial Gardens, hundreds of invaluable Chinese art masterpieces and antiquities were stored in the halls, making the Imperial Gardens one of the largest museums in the world. Some unique copies of literary work and compilations were also stored inside the Imperial Gardens.
