There is a group of Round Barrows on the hill brow looking North towards Petersfield/Langrish. The barrows are marked on the Info boards close to a recommended walk around the crown of the hill. I can't believe there was no IA activity atop Butser. There's clearly no hillfort but it would have been a fine sister to Old Winchester Hill. There was Neolithic activity all around too with Flint Mine (scatters) on nearby Windmill Hill (no not that one) and plenty of axes found around Petersfield.
The hillside is covered by an ancient field system and finds at the top indicate an Iron Age settlement up there. I have to admit to not having seen many signs of ancient remains, but I wasn't hanging around to look to be honest..
Excellent views though.
Nearby, in the Country Park, the type of settlement it is thought to have been has been recreated (See links).
