The Seventeen-Arch Bridge spans Kunming Lake in the Summer Palace in Beijing, linking the East Causeway to South Lake Island. Built in the Qianlong era of the Qing, it is about 150 metres long and is the largest stone bridge in the garden; more than five hundred stone lions, each in a different pose, crown the posts of its balustrade. Official Qing stone bridges usually have an odd number of arches, and Liang Sicheng cites this one together with the Marco Polo Bridge. The Summer Palace is a World Heritage Site.
