The Round City (, "Tuancheng") has as its main structure the Hall of Received Light ("Chengguangdian"), a spacious building with a double-eaved roof made of yellow glazed tiles bordered in green. Inside there is a 1.6 m tall Buddha presented to the Guangxu Emperor of the Qing dynasty by a Khmer (Cambodian) king. It is carved from a single piece of pure white jade inlaid with precious stones. The Eight-Nation Alliance damaged the statue's left arm in the Battle of Beijing in 1900.
