Monnow Bridge (Welsh: Pont Trefynwy) in Monmouth, Wales, is the only remaining fortified river bridge in Great Britain with its gate tower standing on the bridge. It crosses the River Monnow 500 metres (1,600 ft) above its confluence with the River Wye. According to tradition, construction of Monnow Bridge began in 1272 to replace a Norman timber bridge. Through the medieval era, the English Civil War, and the Chartist uprising, the bridge played a significant role in defending Monmouth. It also served as a toll gate, a gaol, a munitions store, a lodge, an advertising hoarding, and a focus for celebrations. Built predominantly of Old Red Sandstone, the bridge was significantly reconstructed in the 18th and 19th centuries. It then also became a popular subject for artists such as Turner. In the 20th century, it suffered damage from accidents and heavy traffic. After a new road bridge was built downstream in 2004, use of the Monnow Bridge was restricted to pedestrians. Its historical and architectural importance are reflected in its status as a Scheduled Monument and a Grade I listed building. (Full article...)
