“The Castles and Town Walls of King Edward I feature some of the world’s finest examples of technical structure, military engineering and Medieval might, so we’re immensely proud to welcome delegates from across the heritage industry to explore these impressive monuments during the WH:UK conference.

World Heritage Sites are selected by UNESCO as landmarks with cultural, historical or scientific significance – and the castles and town walls of King Edward in Gwynedd were chosen in this respect as world-class examples of late 13th century and early 14th century military architecture in Europe.
