Talybont Castle is a circular, ditched, flat-topped mound, c.32-5m in diameter, the counterscarp of which extends to enclose an irregular area, c.50m E-W by 40m, to the S. Erosion to the motte revealed it to have been based on a natural mound. Royal Commission aerial photography in drought summers has clearly revealed the plough-levelled ditches of the former bailey, with an obvious gateway, as well as wider-spreading ditches possibly representative of outer defences or annexes.
