This motte is in an advanced state of decay. It was excavated in 1933 when it consisted of a rectangular mound 100' E-W by 70'. In 1933 it stood 11' above ground level. It was bordered on the S side by the Antonine Ditch and on the other three sides by a ditch, 17' wide and 6' deep. The mound consisted of a slight natural knoll, rising about 6' above the general ground level, to which a layer of clay soil about 5' in depth had been added. Amongst the few relics found was an unstratified pottery fragment dated to c.1200.
The motte is referred to as 'lie Mot de Seybeggis' in a charter of 1542, while in 1797 it was known as the 'Mote'.
