Xiānnóng Altar & Běijīng Ancient Architecture Museum
This altar – to the west of the Temple of Heaven – was the site of solemn imperial ceremonies and sacrificial offerings. Here you'll find the excellent Běijīng Ancient Architecture Museum, which informatively narrates the elements of traditional Chinese building techniques. The museum is spread over the four 15th-century halls which face one another across the large courtyard. Each features different exhibits, but the centrepiece is the magnificent Jupiter Hall (太岁殿; Tàisuì Diàn), with exquisite detail in its ceiling.
