Beihai Park is one of the oldest parks in Beijing. The lake and artificial hills were first built in 1179 and additions were made during the successive dynasties. White Dagoba atop the hill was built in 1651. Halls, pavilions and other buildings are connected by winding galleries, tunnels, stairways and footpaths. Among the famous spots in the park are the Nine-Dragon Screen and the Five Dragon Pavilions, Kublai Khan used to live here.
