Jiumenkou: Where a Wall Must Let Water Through
Nine openings reveal the practical problem of maintaining a boundary across a river.
At Jiumenkou in Suizhong County, the Great Wall crosses the Jiujiang River on a pier-supported structure. Water passages and paved stonework form part of a crossing protected by adjoining fortifications. Excavation in the 1980s informed the restored presentation seen today, so its readable form also records modern archaeological work.
