Chepstow - Geography

Geography

Chepstow is located on the west bank of the River Wye, some 3 miles (4.8 km) north of its confluence with the Severn estuary. To the north of the town, the Wye passes through a limestone gorge, and there are limestone cliffs at Chepstow both north and south of the town centre and on the opposite (east) side of the river. The town is overlooked by the inland cliffs at Wyndcliff near St Arvans, about 2 miles (3.2 km) north of the town, and, from parts of the town, the Severn estuary and its bridges can be seen. The historic centre of Chepstow occupies part of a bend in the River Wye, and slopes up from the river to the town centre and beyond. The underlying geology is of carboniferous limestone. As well as cliffs used for rock climbing, there are cave systems in the area including Otter Hole, one of the longest cave systems in Britain and noted for its mineral deposits. The climate of the town is affected by its position close to the Severn estuary.

The River Wye at Chepstow has one of the highest tidal ranges in the world. The river was established as a boundary between England and Wales by Athelstan in 928. However, after the Norman conquest, areas east of the Wye, within the former Saxon royal manor of Tidenham and including Beachley, Tutshill, Sedbury and Tidenham Chase, were included within the lordship of Striguil or Chepstow. In 1536, the river was confirmed as the boundary between Monmouthshire and Gloucestershire. Since the early 19th century, housing development has continued on the east bank of the river opposite Chepstow, at Tutshill and Sedbury. Those areas, though located in England rather than Wales, are now effectively suburbs of the town.
