Knag Burn Gateway

The Knag Burn Gateway is a gateway which was built into Hadrian's Wall some time after construction of the wall itself, generally acknowledged to be during the fourth century [1]. Knag Burn Gateway is located at the point where Hadrian's Wall crosses the Knag Burn, just to the east of Housesteads [1]. Knag Burn Gateway is one of the few gates through the wall that isn't part of a milecastle or fort [1]. The remains indicate that the structure consisted of a single-lane gateway, with guard-chambers on either side and a gate at each end, thus allowing two-stage controlled passage through the wall [1]. Professor I. A. Richmond suggested that the gateway was constructed to allow trade traffic through the wall some time in or after the fourth century [1]. The gateway was discovered in 1855 and excavated in 1936 and 1988 [1].
