Morgraig Castle has been described as a certain Masonry Castle.

There are masonry footings remains.

This site is a scheduled monument protected by law.


Castell Morgraig was built by the Anglo-Norman de Clare lords of Glamorgan, sometime after 1243 and before 1267, when it was abandoned unfinished as the de Clares defeated the last Welsh native lord in the area and started building Caerphilly nearby. (Iorweth quoting Jack Spurgeon)

Morgraig Castle is thought to have been raised in the mid thirteenth century and possibly never completed. The site consists of a rather irregular pentagonal enclosure, c.38-42m in diameter, defined by walls and towers.. (Coflein)

Castell Morgraig is a ruined medieval Castle, on the ridge top, with a steep drop to the Cardiff plain to the south. The castle has a rectangular plan, with bastions in all four corners. Those on the N side are pentagonal, that on the SW corner has a rounded end, and that on the SE corner is also pentagonal. From a partial excavation in 1903-4 it was concluded that the castle was of C13th date and was never finished. (Glamorgan-Gwent Archaeological Trust HER)

The monument comprises the remains of a castle, dating to the medieval period. It is located on the southern boundary of the Welsh lands of Senghennydd Is Caech on a ridge top overlooking the Cardiff plain. The ruined remains consist of a walled pentagonal enclosure about 40m in diameter with the angles defined by the remains of four towers and on the east a keep. It is thought to have been built in the mid thirteenth century and may not have been completed. (Scheduling Report)
