Dinas Emrys

Dinas Emrys is a steep, volcanic outcrop of rock that looms over Nantgwynant ' the beautiful valley that stretches north-east of Beddgelert. An impressive sight in any weather, it's worth walking up to the summit, where the masonry base of a medieval tower can still be seen. This is all that remains today of a keep, believed to have been constructed at the end of the 12th century when there was a struggle for supremacy among the princes of Gwynedd.
