Hugh Lupus, Earl of Chester, while carrying on his desolating warfare against the Welsh, landed his forces at Cadnant, in the parish, in 1096, and, having encamped on the summit of an eminence called Dinas, at the upper extremity of the vale, commenced a series of devastations, which were characterized by the most barbarous and atrocious outrages.

Some vestiges of the camp constructed by Hugh Lupus at Cadnant are still visible, and near them are the remains of a small circular building. (Lewis 1849)

Gatehouse Comments

The remains are actually of an Iron Age hillfort and defended early medieval settlement although use of these earthworks by Hugh can not be excluded.
