What is recorded here
Castell Trefesgob stands as a scheduled monument on raised ground west of Bishton Road, marking the lost seat of the Bishops of Llandaff before Owain Glyndŵr destroyed the palaces at Bishton and Llandaff. The site preserves the medieval roots of Bishopston, where Bishop John Pascall died of the plague in 1361 and Guidnerth received land near St. Cadwaladr's church around the year 700. These are the remaining facts about the castle and its surrounding town.
The National Monuments Record of Wales records Castell Trefesgob; Bishton Castle; Langstone 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.
Bishton Castle, also known as Langstone Castle or Castell Trefesgob, was built in the late 13th or early 14th century by the de Lacy family, Anglo-Norman lords of the region. It is remembered as a strategic medieval stronghold in the Welsh Marches, reflecting the turbulent history of border defense between England and Wales.
The historic-place record does not grant public access. Check current conditions and ownership before entering land or a building.
