Isle of Portland - Geography

Geography

The Isle of Portland lies in the English Channel, 3 kilometres (2 mi) south of Wyke Regis, and 200 km (120 mi) west-southwest of London, at 50°33′0″N 2°26′24″W / 50.55°N 2.44°W / 50.55; -2.44 (50.55, −2.44). Portland is situated approximately halfway along the UNESCO Jurassic Coast World Heritage Site; the site includes 153 kilometres (95 mi) of the Dorset and east Devon coast that is important for its geology and landforms. The South West Coast Path runs around the coast; it is the United Kingdom's longest national trail at 1,014 kilometres (630 mi). Portland is unusual as it is connected to the mainland at Abbotsbury by Chesil Beach, a tombolo which runs 29 kilometres (18 mi) north-west to West Bay. Portland is sometimes defined incorrectly as a tombolo—in fact Portland is a tied island, and Chesil Beach is the tombolo (a spit joined to land at both ends).

There are eight settlements on Portland, the largest being Fortuneswell in Underhill and Easton on Tophill. Castletown and Chiswell are the other villages in Underhill, and Weston, Southwell, Wakeham and the Grove are on the Tophill plateau. Many old buildings are built out of Portland Stone; Several parts have been designated Conservation Areas to preserve the unique character the older settlements which date back hundreds of years. The architecture; the natural and man-made environment and the proximity to the sea give Portland overall character which is quite distinct.
