Penrhyn Castle is a country house in North Wales, in the form of a Norman castle. It was originally a medieval fortified manor house, founded by Ednyfed Fychan. In 1438, Ioan ap Gruffudd was granted a licence to crenellate and he founded the stone castle and added a tower house. Samuel Wyatt reconstructed the property in the 1780s.

Caernarvon is architecturally one of the most impressive of all of the castles in Wales. It's defensive capabilities were not as overt or as powerful as those of Edward I's other castles such as Harlech and Beaumaris (which indicate the pinnacle of castle building and defenses in Britain), but Caernarvon was instead intended as a seat of power - and as a symbol of English dominance over the subdued Welsh.
