Prince Kung's Mansion, also known as the Prince Gong Mansion, is a museum and tourist attraction located in Xicheng District, Beijing, just north of the Shichahai Lake. It consists of large siheyuan-style mansions and gardens. Originally constructed for Heshen, an official highly favoured by the Qianlong Emperor, it was later renamed after Prince Gong, a Manchu prince and influential statesman of the late Qing dynasty, who inhabited the mansion in the late 19th century.
