Although originally established soon after 1100, much of the castle dates from C14 and later. Parts were rebuilt following the siege by Owain Glyn Dwr in 1404-5. Sub-circular ditched enclosure, c.36-42m in diameter, with sub-rectangular enclosure, c.55m E-W by 36m, attached on the W, both are defined by ruins of towered cutain walls, with extensive remains of internal buildings. Castle thought to have been established in early C12, continuously occupied and added to up to C16, with occupation extending into the early C18. By C18 the castle was mostly ruined. The castle consists of a circular inner ward, with three story keep on NW side and C14 domestic block to the S side. To the NE of this block is the chapel, the interior of which only survives at basement level. A well has also survivied in the inner ward, along with some stone paving. The inner ward is enclosed on the N, E and S sides by a ditch with a faceted curtain wall, on the W side of which is an outer ward with curtain wall. The high outer ward curtain wall features a C15 gatehouse to W, which is now the main entrance.
