Llangibby, 3 miles South of Usk
Llangybi Castle,formerly known as Tregrug, occupies a wooded plateau above the village. The single fortified enclosing wall encircles the entire plateau, being 540 feet long and 270 feet at its widest point.
It is probably the largest castle enclosure in England and Wales and possibly the largest in Europe.
There is also a massive Edwardian gatehouse. In summary, this place is massive.
We first heard of this castle from the BBC Time Team visiting the site some years ago and set about looking up where this massive forgotten castle was.
The original motte and bailey castle was set behing castle farm just off the main road, albeit nothing now remains. From the main road with its impressive entrance up a long driveway into the estate, you will arrive at a number of buildings belonging to the estate management and owners. As this site is on private land you must seek permission first.
We were absolutely delighted to be allowed to explore the ruins but nothing could prepare us for what we found. How such a massive castle could remain hidden from the world is a wonder in itself.
A walk round the ruins you soon get a feel of the scale of the place.
The much ruined overgrown gatehouse must be comparable to the one at Caerphilly Castle. There are also some beautifully carved features in some of the towers and domestic buildings.
If you are fortunate to be allowed access to this very special castle, do take care and give due consideration to the permission granted by the kind owners. A sensational 'castle-finder' discovery if you are very lucky.
