The twin crags that go to make up Degannwy castle. The
fortress has a long history that dates back to post Roman times.
By the late 1080s it was held by the Breton, Robert Rhuddlan, who
died in action beneath the fortress walls in 1093. The castle
then passed back and forth between 'Norman' and Welsh ownership.
The site was massively rebuilt by Henry III in the 1240s, but destroyed
by Llywelyn ap Gruffydd in 1263. Edward I began to rebuild it in
1282, but abandoned the work in favour of Conway castle across the
The main work, comprising a masonry enceinte with projecting D-shaped
towers, lies on the rock to the west (left). The Mansell tower,
named after one of Henry III's ministers, lay on the crag to the east
(right). A tower on the north side of the rock is of similar dimensions to the tower at Pen y Bryn.
