The Baoguo Temple stands on Mount Ling in Jiangbei District, Ningbo. Its main hall, built in the early eleventh century under the Northern Song, is among the oldest timber buildings south of the Yangtze. The bracket sets inside are dense and the caisson ceilings finely made, among the earliest surviving timber caissons; the construction closely matches the Yingzao Fashi, the building manual issued some decades later. Liang Sicheng first took the Sanqing Hall at Suzhou as the oldest timber building in Jiangnan; earlier Northern Song examples such as the Baoguo hall were found afterwards.
