1272 Fortified stone Monnow Bridge

Monnow Bridge in Monmouth, is the only remaining mediaeval fortified river bridge in Great Britain with its gate tower still standing in place. It crosses the River Monnow some 500m above its confluence with the River Wye. The stone bridge is constructed of Old Red Sandstone, with three arches on hexagonal piers forming pointed cutwaters. The gatehouse, called Monnow Gate, which gives Monnow Bridge its remarkable and noteworthy appearance, was added at the end of the 13th or start of the 14th century, a few years after the bridge itself was built.
