Overview

History & significance

Llangibby Castle, also known as Castell Tregrug, is a medieval castle situated in Monmouthshire, Wales. The site consists of a motte-and-bailey earthwork of Norman date, representing a characteristic early medieval defensive settlement of the post-Conquest period. The castle occupies a strategically important location within the Welsh borders and reflects the pattern of Norman plantation in the region during the twelfth century. Though now largely reduced to earthwork remains, the site retains considerable archaeological significance as evidence of early medieval fortification strategy in South Wales.
