Dinas Castle (Castell Dinas)
Near Blaenllyfni, Powys
Not to be confused with the more well-known Castle Dinas Bran in Denbighshire, Dinas Castle is the meagre remains of a very early Norman building. It seems likely that the castle was overrun by the Welsh in 1233, and again in 1262. What little remains of the Norman masonry is overgrown with greenery.
