Castles and Town Walls of King Edward in Gwynedd
The location of the castles in Caernarfon and Conwy were chosen for their political significance and their military uses. The castles include luxury apartments and gardens. Caernarfon's castle and town walls had expensive stonework. They were perhaps made to suggest images of Arthurian or Roman imperial power. They are believed to have been made to improve Edward's personal prestige.
