Tretower Castle (Welsh: Castell Tretŵr) is a Grade I-listed ruin, built around the beginning of the twelfth century as a motte and bailey castle and this was probably replaced mid-century by a stone shell keep. The castle was enlarged in the early thirteenth century, but later fell into ruin. Tretower Court is a medieval fortified manor house that evolved from the adjacent Tretower Castle site. It is a rare example of its type, in that it shows the way in which a castle gradually developed into another significant type of medieval building. Both are in the care of Cadw.
Tretower Court is supposedly haunted by a White Lady. Some claim that this could be the ghost of Roger Vaughan's wife, the Vaughan family being owners of this site from the 14th-18th century. The ghost of another female has been reported in the main bedchamber, and a small boy has been sighted on the steps to the courtroom.
