Penrhyn Castle is a country house in Llandygai, Bangor, Gwynedd, North Wales, in the form of a Norman castle. It was originally a medieval fortified manor house, founded by Ednyfed Fychan.

Castell Coch
The first castle on the Castell Coch site was probably built after 1081, during the Norman invasion of Wales. It formed one of a string of eight fortifications intended to defend the newly conquered town of Cardiff and control the route along the Taff Gorge.
