To the East of St Peters church is a circular motte 43yds in diameter surrounded by a dry ditch with outer rampart extending for 20yds along the West side and widening at the South end into a slight mound.

Around the top of the mound are traces of rubble walling of a dormer keep or structure, but it is now mostly covered with soil. On either side are traces of scarps, banks etc, most probably of a later date.

On the North side are scarps enclosing a small stream, which would have possibly formed additional defences.

40yds NW of the motte is a small rectangular mound about 2ft high and in the field on the E side of the stream, 190yds E of the motte, is a small portion of deep ditch and traces of banking.

The motte has soil covered wall 3-4ft high around its summit. The ditch and outer bank are very clear except where the bank has been removed to drain the ditch. Masonry reveals a shell keep and foundations of a building on the very West Side of the bailey. The farmer believes that the land has never been ploughed.

The castle is thought to have been built by Richard Esketot, a tenant of the de Lacy’s of Longtown, c 1090’s.
