Cadw's description
Summary description and reason for designation
The following provides a general description of the Scheduled Monument.
A motte and bailey with the foundations of rectangular structures and enclosures NE and W of the motte.
The top of the motte stands some 9m above the level of the bailey, and is 12m in diameter. The top has been severely damaged by trenches dug across it; the principal trench is 6m across and nearly 2m deep.
The body of the motte is mainly of stone, and revetted stonework is still visible on the sides of the motte, although blackthorn obscures much of this work. The bailey also makes use of natural outcrops of rock, and is defended on the W by a bank 3m wide and 0.6m high. There is a small, rock-cut pool in the SW corner of the bailey.
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 structures themselves 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.
