The site is exposed but has very wide views in all directions, especially to the NW, N and NE, with the double wall on the S and E and the entrance on the E. A sheepfold effectively obscures any remains of guard-houses. There is a number of hut-circle depressions and platforms in the interior, but there is little stone and the blanket of vegetation makes it very difficult to say what that number might be. Similarly, the bank and ditch of the extension to the S are well disguised, although the stone wall on the W side of this, although collapsed, seems to have been strongly built - was it intended to continue this all the way round? The solid, square structure on the highest point of the settlement is probably the remains of an eye-catcher built as a Nannau estate feature: various forms of these are numerous throughout the estate.

The monument is of national importance for its potential to enhance our knowledge of prehistoric settlement and defence. It retains significant archaeological potential, with a strong probability of the presence of associated archaeological features and deposits. The structures themselves may be expected to contain archaeological information concerning chronology and building techniques.

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