Llangibby Castle

Also known as, or recorded in historical documents as; Castell Tregrug; Tregreg; Trigruck

In the community of Llangybi. In the historic county of Monmouthshire (Modern authority of Monmouthshire, preserved county of Gwent).

Roughly rectangular bailey 150m long by 80m wide. Only slight footings remain of a twin round towered gatehouse and a D-shaped tower on the south side plus two eastern towers, and not much more of the curtains which joined them, but the 2m thick north curtain with one D-shaped tower is intact, and there are two large structures of great interest at the west corners. That on the SW is a huge gatehouse with long U-shaped towers flanking a passageway closed formerly by portcullises and sets of doors. The NW corner of the bailey is occupied by a rectangular tower house 10.4m wide with round turrets at the east corners, that on the south having a spiral stair, and that on the north containing a hexagonal room formerly vaulted. The round west end shows signs of having been blown up in 1648. It is 12m in diameter.
