This domed hilltop will be familiar to many people who live, work, or drive along the coastal plain near Chichester but especially to those heading to Goodwood for the racing.
Few probably realise that the hill overlooking the course hosts the startling remains of an Iron Age hillfort which in turn lies on top of the remains of very rare Neolithic enclosures.
The hillfort, with its large bank and ditch, is prominent and the highest point once hosted St Roche's church, now marked by a heavily disturbed mound.
The two enclosed modern compounds are what remains of an early warning radar system built during the Second World War.
The site is best approached from the car park to the west of the hillfort - the walk here isn't particularly steep but the views over the coastal plain are magnificent.
