Criccieth Castle, Gwynedd

CADW
Criccieth Castle is a native Welsh castle whose remains dominate the coastal town of Criccieth. The castle was apparently commenced at the beginning of the 13th century. Later, it was occupied for a time by the English, who are thought to have remodelled it. It was destroyed by the Welsh during Owain Glyndwr’s rebellion in the 14th century.
The remains are dominated by the gatehouse, which looks like an English design but was almost certainly built by the Welsh. There are superb views from the castle mound as far as Harlech, Snowdonia, etc. Bring your binoculars.
The castle is worth a visit if you are in the area. Given its ruined state, looking at the castle will not detain you very long.
