Sited on the summit of a shoulder of land overlooking Harehope Burn, these earthworks include strong, natural defences on the north, east and south-east side. On these sides the naturally steep slopes have been altered to make them even more formidable. Two banks defend the weaker west side. The outer bank survives up 2.5m, and the ditch is in places up to 3m deep. Hillforts such as this site belong to the Iron Age. It is a Scheduled Monument protected by law.
