Main image

Conwy Castle is a late 13th-century royal fortress on the north coast of Wales, constructed under the orders of King Edward I during his campaign to conquer Gwynedd. Building began in 1283 and the castle is noted for its well-preserved curtain walls and multiple defensive towers.

Key features include high curtain walls with integrated towers and an inner ward; the castle layout was designed for strong defence and to dominate the town and estuary. Many visitors walk the battlements and explore the towers and gatehouses to see period defensive architecture and views across the estuary and town.

Edward I commissioned the castle as part of a strategic ring of fortifications in North Wales in the late 13th century; it has since seen military use, sieges and later preservation. The site has been conserved and is managed for public access.

Conwy Castle stands on the tidal estuary of the River Conwy within the walled medieval town of Conwy in North Wales, overlooking water that connects to the Irish Sea and positioned near other North Wales seaside towns.

  • UNESCO listing: Part of the UNESCO World Heritage site 'Castles and Town Walls of King Edward in Gwynedd' and typically visited together with the town walls and quay.
  • Visitor tip: The castle's battlements and towers offer extensive views across the Conwy estuary and the 19th-century Conwy Suspension Bridge; bring sturdy footwear for steep steps.
