What is recorded here
Castell Tregrug stands in ruins beside Llangybi, a medieval castle marked in the national record but never defined in the available facts. The valley around it belongs to Cybi, whose name is on the church and well, yet the castle itself resists easy dating or ownership. What remains is a gap in the story, not a completed account.
The National Monuments Record of Wales records Castell Tregrug; Llangybi Castle as Castle from the Medieval period. The saved point comes from the official national record. Inclusion does not by itself mean that the public may enter the place.
Built by the de Lacy family in the late 13th century, Llangybi Castle is remembered as a strategic medieval stronghold in the Welsh Marches, reflecting the turbulent history of Norman expansion into Wales.
The historic-place record does not grant public access. Check current conditions and ownership before entering land or a building.
