Adi Shankara established Badrinath as a pilgrimage site in the ninth century. The temple has three structures: the Garbhagriha (sanctum), the Darshan Mandapa (worship hall), and Sabha Mandapa (convention hall). The conical-shaped roof of the sanctum, the garbhagriha, is approximately 15 m (49 ft) tall with a small cupola on top, covered with a gold gilt roof.[6][8] The facade is built of stone and has arched windows
