This Iron Age hill fort fills perches on the Greensand ridge that crosses the county here. Most of the hillside is wooded, but you can see some ditches. There is a monumental vista (for this part of the world - it's all relative) and you can sit on the sandy rabbit-nibbled turf, mull things over and watch the intercities thunder by on the main line north. Best on a sunny day maybe.
With regard to the name - obviously it's traditionally associated with the Romans, which in a way is unsurprising because several Roman villas have been found fairly locally.
