Portland is a tied island, connected to the mainland of Dorset by Chesil Beach, a tombolo stretching eight miles.

The Isle of Portland's strategic location has made it a significant site for coastal defence, with fortifications dating back to Roman times.

Portland stone, a distinctive white limestone, has been quarried on the island for centuries and used in iconic buildings like St. Paul's Cathedral and Buckingham Palace.

Historically, Portland was a royal manor, and its ownership and control have been subject to various royal grants and charters.

Portland's economy has been heavily reliant on quarrying and its naval base, although tourism has become increasingly important in recent years.

The island experienced considerable population growth during the 19th century due to the expansion of the naval base and quarrying industry.

The Portland Bill Lighthouse, located at the island's southern tip, has guided ships through the English Channel for centuries and is a notable landmark.

The island's unique geological features contribute to its part in the Dorset and East Devon Coast UNESCO World Heritage Site, also known as the Jurassic Coast.

Portland Harbour, one of the largest man-made harbours in the world, played a critical role as a naval base during both World Wars.

The island has a strong maritime heritage, with a long history of shipbuilding, fishing, and naval activity.

The Verne Citadel, a 19th-century fortress, served as a prison for many years and offers panoramic views of the surrounding coastline.

Portland's close-knit community retains unique local traditions, including the 'Portland Lobster Pot' race, an annual event that showcases local seamanship.

While Portland is not known for any major political movements, its history is closely tied to national naval power and defense strategies.

The island's rugged coastline and diverse habitats support a variety of flora and fauna, making it a popular destination for birdwatching and nature enthusiasts.

Despite its relative isolation, Portland has seen a recent increase in residential development and tourism-related infrastructure, reflecting a shift towards diversification of its economy.
