The monument consists of the remains of a castle, dating to the medieval period. Skenfrith is one of the Three Castles (with White Castle (MM006) and Grosmont Castle (MM007)) and was probably built around 1070 by William Fitz Osbern. The orignal castle would have been of earth and timber construction surrounded by a deep defensive ditch and with a stone built-keep. Evidence for these features has been found through excavation. All of the visible castle structures were built by Hubert de Burgh between 1219 and 1232, at the same time as he was rebuilding Grosmont Castle. He built the curtain wall around a roughly rectangular area within which he built the central round tower and ranges of living quarters. The western living quarters retain original architectural details such as iron bars set into windows and shutter hinges. On the outer side of the curtain wall rectangular holes to hold beams that supported wooden fighting galleries can be seen, and the castle would have originally been surrounded by a deep moat. The final phase of building at the castle was the addition of a semi-circular tower mid-way along the south-western wall. This was built sometime in the later 13th century and may have been the work of Lord Edward, Henry III's eldest son and later Edward I, when he owned Skenfrith.

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.
