The monument comprises the remains of a hillfort probably dating to the Iron Age (800 BC – AD 74). It is located on the summit of a small steep-sided hill at 150m above OD.
It measures 65m long from east to west by 30m wide enclosing 0.2ha, and is defended by a bank following the contours of the hill. The bank is 0.3m high internally but with an outer scarp nearly 3m high. At the eastern end is a simple entrance 4.5m wide. Outside the bank is a berm 6-7m wide, followed by a second rampart. This is missing on the north-eastern and along the eastern half of the northern side; along the western half of the north side it is visible as a bank 3m wide and 0.6m high. It is best preserved across the western end where it is 6m wide and nearly a metre high; along the southern side it forms a scarp fading into the natural slope. The entrance is on the east and is 14m wide; outside it are traces of an approach road winding up the hill.
The monument is of national importance for its potential to enhance our knowledge of late prehistoric defensive organisation. The monument forms an important element within the wider Iron Age context and may be expected to contain archaeological information in regard to elements such as chronology, building techniques and social organisation.
