Porth yr Aur

[1] Porth yr Aur forms part of the Castles and Town Walls of King Edward in Gwynedd UNESCO world heritage site.

[3] Porth Yr Aur and the town walls were constructed on the instruction of Edward I in order to consolidate his conquest and occupation of North Wales on 1283.

[1] The walls and castle were built under the direction of James of St George, who was Edwards military architect in North Wales, and cost £3500 by completion in 1292.

[1] Following the English Civil War maintaining the Castles defences became less important, although seven canons were installed on Porth Yr Aur in the 1790s to defend against the threat of Napoleonic invasion.

[4] The decline of the walls was arrested in the 19th century as parts were acquired for use in housing and offices, as the towns population expanded significantly due to the booming slate trade[3] Porth Yr Aur was acquired by the recently formed Welsh Royal Yacht Club in 1854 and was remodelled and restored to fit this new purpose.
