Cadw's description

The following provides a general description of the Scheduled Monument.

The monument comprises the remains of a medieval castle, with important historical associations as a possible predecessor to nearby Dolwyddelan Castle. It is sited on a prominent natural rock outcrop, naturally defended on the N, S and E by a very steep rocky precipice. On the W the slope is slightly more gradual, but still very steep.

The natural defences are complemented on the W and NW by a ditch, now very silted but clearly recognisable, especially on the W. The top of the mound is somewhat uneven and on the summit are traces of a rectangular structure, perhaps 6m x 6-7m, probably the base of a tower. The foundations are most clearly seen on the E side.

The monument is of national importance for its potential to enhance our knowledge of medieval settlement and defence. It retains significant archaeological potential, with a strong probability of the presence of associated archaeological features and deposits. The structure itself may be expected to contain archaeological information concerning chronology and building techniques.

The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
