This impressive building, which houses the palace which was once used as a summer residence of Chinese emperors, is one of the most visited monuments of Beijing. To visit and see everything you'll have to spend at least all morning doing it, because there seems to be not only an infinite number of buildings, but also forests, temples, gardens, hills and lakes. There are always many tourists, especially Chinese ones ve come from other parts of China, but for being so big you will not feel too overwhelmed like what can happen in places like the Forbidden City. Chinese emperors fled here in the summer when the heat was scorching, to situated in the northwest of the city. In its original design there was a real garden, but in the 18th century it was extended, now including Lake Kunming. The last reform that took place was started in 1949, but it was damaged by natural disasters.
