There are eight settlements on the Isle of Portland, Dorset, England,[1] the largest of which are Fortuneswell in Underhill and Easton on Tophill.
Weston contains a Roman Villa - one of the few archaeological sites on the Isle of Portland, which is opposite the Royal Manor Arts College.
The nearby villages of Chiswell and Castletown almost merge into Fortuneswell, as they share the limited space on the northern slopes of the island.
Chiswell (rarely Chesilton) is a small fishing village at the southern end of Chesil Beach, in Underhill.
However this distinction can be made: Chiswell occupies flat land close to sea level, whereas Fortuneswell's streets wind up and down the steep hills.
Over the centuries Chiswell has battled with the sea and has been regularly flooded during rough winter storms which can over top the 15 metres (49 ft) high Chesil Beach which protects the village.
