into ruin after the Civil War. There is a large car park in front of the castle, beside the Tourist Information Centre and opposite Chepstow Museum. The castle is under the management of Cadw, and is open to the public every day of the year, apart from four bank holidays around Christmas and New Year. It is entered through the late-12th-century gatehouse, and contains exhibitions on the castle's history. A footpath beside the castle, through the Dell, is the start and finishing stretch of the Wye Valley Walk. Town Gate and Port Wall Much of Chepstow's late-13th-century Port Wall remains intact, although the stretch south of the railway line was demolished when the National Shipyard was constructed in 1916. The wall is best seen adjoining the main town car park in Welsh Street, or beside the main A48 road at the top of School Hill. It can also be seen adjoining the Gate House, which was built in 1609 beside the Town Gate at the top (western) end of the High Street. The Town Gate, now a single carriageway roadway controlled by traffic lights, was once the only point of entrance to the town centre other than the bridge below the castle. It was rebuilt in 1524 and has undergone several renovations since then, most recently in 1986. The Gate House and the room above the archway itself are occasionally opened to the public. Priory Church of St Mary Chepstow Priory was established in 1067, at the same time as the castle. Its Norman west doorway remains intact, as do some mediaeval and later interior features including Jacobean tombs. The Priory Church of St Mary became the town's parish church after the English Reformation. Its tower dates from the early 18th century, and the entire church was substantially rebuilt and extended in the mid-19th century, a process which destroyed some of its earlier features. Bridges and the riverside The Old Wye Bridge below the castle was built in 1816, on the site of earlier wooden bridges. The cast iron structure is noted for its elegance. It now carries a single carriageway road controlled by traffic lights. The eastern end of the bridge, in Gloucestershire, is the start and finish point of the Gloucestershire Way. The riverside area of Chepstow was once an open area of shipyards surrounded by warehouses. It has been landscaped, to incorporate flood defence works, and is
