The monument comprises the remains of a motte and ditch, dating to the medieval period (c. 1066 -1540 AD). A motte is a large conical or pyramidal mound of soil and/or stone, usually surrounded by either a wet or dry ditch, and surmounted by a tower constructed of timber or stone. Tomen Rhyd-Owen stands c.4m high on the west and drops down a steep slope to the Afon Clettwr on the east; the summit is flat, c.10m in diameter. There are slight traces of a ditch on its west. At the foot of the mound on the north is a small rectangular enclosure c.9m square.

The monument is of national importance for its potential to enhance our knowledge of medieval defensive practices. The monument is well-preserved and an important relic of the medieval landscape. It retains significant archaeological potential, with a strong probability of the presence of both structural evidence and intact associated deposits.

The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
