The defences are best preserved on the W side, where there is an outer bank 0.3-0.5 m high, a fall to the bottom of the ditch of about 1 m and then a climb of 2 m to the top of the internal bank. The internal bank lies between 0.75 and 1.5 m above the level of the interior. The ditch has been filled in on the E and NE sides, but is still just visible. It is possible that the ditch was filled with water from the adjacent stream.
A modern field bank cuts through the S part of the site, causing some damage to the banks. The site is generally better preserved S of this wall, although parts of it are very overgrown with thorn and bramble.
A 2 m gap in the interior bank on the E side may represent the original entrance. A shallow gully, possibly a modern drain, runs from the N side of the site. The remains of a bank can be seen in the undergrowth S of the field wall and 10 m W of the outer bank. Its purpose or extent could not be determined.
The monument is of national importance for its potential to enhance our knowledge of medieval practices. It retains significant archaeological potential.
