:"A considerable portion of the north gate of Lincoln — the Newport Arch — is standing, but is buried to the extent of about . in the soil and débris accumulated since Roman times. The structure is about . deep and has a single passage for the road, 17½ ft. wide. The inner or back portal of this passage is still intact, and is nearly . in the clear and rises to a height of about 22½ ft. above the Roman level. Its arch is of a single ring of large limestone voussoirs rising from imposts which appear to have been moulded. The outer or front arch has long since disappeared. On the east side is a postern for pedestrians, . wide and contracting to about . at the north end, and . high from the Roman level. On the west side there was a similar postern about a century ago. The whole structure is of good masonry, and it appears to have projected considerably beyond the north face of the town wall."
