Turret 50A (High House) (grid reference NY60206586) was excavated in 1911.[3] The north half of the turret is buried beneath the road, and the south half survives as a slight earthwork at the edge of the adjoining field.[3] It replaced the earlier turf wall turret (50A TW; grid reference NY60276569) which was dismantled when the stone wall was built.[4]
