Castles and Town Walls of King Edward in Gwynedd UNESCO World Heritage Site

Medieval castles, fortified towns, and historic landscapes across north Wales

The Castles and Town Walls of King Edward in Gwynedd UNESCO World Heritage Site brings together a series of medieval fortifications across North Wales, including Conwy, Caernarfon, Harlech, and Beaumaris. Built during the reign of King Edward I in the late 13th century, these castles and town walls represent one of the most significant surviving systems of medieval military architecture in Europe.

Located across the landscapes of Gwynedd and connected to routes linking the coast, mountains, and historic settlements of north Wales, the site forms part of a wider network of places shaped by centuries of history and movement through the region. The castles and town walls connect medieval heritage, cultural landscapes, and some of the most recognisable historic landmarks in Wales.
