Newport Arch

Newport Arch is a 3rd-century Roman gate in the Newport district of the city of Lincoln in Lincolnshire [1]. It is a Scheduled monument and Grade I listed building and is reputedly the oldest arch in the United Kingdom still used by traffic [1]. The arch was remodelled and enlarged when the city, then the Roman town Lindum Colonia, became capital of the province Flavia Caesariensis in the 4th century [1]. The structure is about 34 ft deep and has a single passage for the road, 17+1⁄2 ft wide [1]. The inner or back portal of this passage is still intact, and is nearly 16 ft in the clear and rises to a height of about 22+1⁄2 ft above the Roman level [1]. Its arch is of a single ring of large limestone voussoirs rising from imposts which appear to have been moulded [1].
