Phillips notes that the site of Castell Arnallt comprises a large, oblong mound (with large surface area at 10,671.346mÃ‚Â³, elevated by a 43% gradient to a maximum height above natural of 8.19m) lying in pasture land by the side of the River Usk which is currently used as grazing land. In a good state of preservation, it is stated that the long axis of the mound can be divided into two areas. Examination of the site suggest that the mound has a series of possible masonry walls across the surface indicating that it is very near to its original height, and that the mound had a good number of sub-surface structures of more than one phase of construction. Phillips notes that there is the possibility of a gate structure to the west side of the upper mound, and interprets the site as a Llys (pre-1175) using natural formations with no raised motte and utilised as a centre of administration (Phillips 2004).
