What is the oldest castle in Wales?

 

The outstanding Castell Cas-gwent (Chepstow Castle) boasts many claims to fame including being Britain’s oldest surviving post-Roman stone castle. Building work began in 1067 by Earl William fitz Osbern, close friend of William the Conqueror, making it one of the first Norman strongholds in Wales. The castle’s Great Tower, modelled upon that of Falaise in Normandy, is the earliest datable secular (non-religious) stone building in Britain, and the structure’s doors are the oldest castle doors in Europe (now on display in the structure’s interior).

Historical significance aside, the castle itself is a wow-worthy structure. Extending along a narrow clifftop ridge, it watches over a long-established crossing of the River Wye, the border between Wales and England.
