Tophill

Tophill is a gently sloping area of land on the Isle of Portland in Dorset, England, rising from sea level at Portland Bill to 151 m near HMP The Verne at its northern end. On Tophill are five of the settlements on the island: Easton, Weston, Southwell, the Grove and Wakeham. Portland stone lies under Tophill, and the strata decline at a shallow angle of around 1.5 degrees from their peak down to sea level. The lower northern end of the island is called Underhill.

In the north-west corner of Tophill is Tout Quarry, whilst the nature reserve King Barrow Quarry lies at the north-east. Near the northernmost point lies the area known as New Ground used as a lookout point, in front of which sits the Portland Cenotaph.
