Portland Raised Beach refers to small raised beaches on each side of Portland Bill, on the Isle of Portland, part of the Jurassic Coast in Dorset, England. The main one is known as the West Pleistocene Raised Beach; nearby is the East Pleistocene Raised Beach.They exhibit multi-type erosion and deposition during a warm spell in the last Ice Age in the inter-tidal zone show signs of tide and wave impact during more recent millennia. For some depth, sandy and shelly pebbles predominate. A factor in the higher than average speed shore erosion is the weight of the ice which covered the north of Britain and beyond in the colder spells that caused the British Isles landmass to tilt (see post-glacial rebound) and prevailing south-west currents and breeze, a pace which results in the relatively little water-eroded cliff-based fossils, stones and pebbles along Chesil Beach. Tidally caught fine material (sand) is deposited on most great bays facing the deeper western half or so of the English Channel and only at narrowings along the increasingly shallow eastern half.

Portland Bill is a narrow promontory (or bill) at the southern end of the Isle of Portland, and the southernmost point of Dorset, England. One of Portland's most popular destinations is Portland Bill Lighthouse. Portland's coast has been notorious for the number of shipwrecked vessels over the centuries. The dangerous coastline features shallow reefs and the Shambles sandbank, made more hazardous due to the strong Portland tidal race.The Bill is an important way-point for coastal traffic, and three lighthouses have been built to protect shipping. The original two worked as a pair from 1716, and they were replaced in 1906 by the current one.

Pulpit Rock is a coastal feature at Portland Bill, the southern tip of the Isle of Portland, Dorset, England. Intended to have the appearance of an open bible leaning on a pulpit, Pulpit Rock was formed in the 1870s after a natural arch was cut away by quarrymen at Bill Quarry, and the leaning slab was added. As a quarrying relic, the rock is similar to that of Nicodemus Knob, another quarrying landmark on the island. Pulpit Rock has become a popular tourist attraction on the island and is often photographed. Despite the danger, for many decades it has been a popular place for tombstoning. Pulpit Rock is also a popular point for wrasse anglers. The British record Ballan wrasse was caught there in 1998 by Pete Hegg.The geological succession up from sea level is: Portland Cherty Series (up to the level of the neighbouring quarried platform), then Portland Freestone (the oolitic limestone quarried inland of Pulpit Rock), then a cap of thin-bedded limestones which are part of the basal Purbeck Formation.

Portland Bill Lighthouse is a functioning lighthouse at Portland Bill, on the Isle of Portland, Dorset, England. The lighthouse and its boundary walls are Grade II Listed.As Portland Bill's largest and most recent lighthouse, the Trinity House operated Portland Bill Lighthouse is distinctively white and red striped, standing at a height of 41 metres (135 ft). It was completed by 1906 and first shone out on 11 January 1906. The lighthouse guides passing vessels through the hazardous waters surrounding the Bill, while also acting as a waymark for ships navigating the English Channel.

The Trinity House Obelisk, also known as the Trinity House Landmark, is a 19th-century obelisk located at Portland Bill, on the Isle of Portland, Dorset, England. Built as a daymark, it has been Grade II Listed since 1978.The obelisk was built in 1844 to warn ships off the coast of Portland Bill. It stands at the southern tip of the Isle of Portland, acting as a warning of the low shelf of rock extending 30 metres south into the sea. The obelisk is made of Portland stone and is seven metres in height. It is inscribed "TH 1844" on its north face. The monument was saved from threatened demolition in 2002 after Trinity House deemed it too expensive to maintain.

Red Crane is a crane on the Isle of Portland, Dorset, England. It is located on the cliff edge at Portland's southerly point, the promontory Portland Bill. It is part of a disused stone loading quay, which is now a scheduled monument.

NCI Portland Bill is a National Coastwatch Institution (NCI) lookout station on the Isle of Portland, Dorset, England. The station is situated 50 metres above sea level on the cliff edge, half a mile north of the tip of Portland Bill. It is located close to the Old Higher Lighthouse. The coast of Portland Bill has been notorious for the many shipwrecks over the centuries. The dangerous coastline has proven more hazardous due to the strong tidal race known as the Portland Race. Portland Bill remains important as a way-point for coastal traffic.

The Old Higher Lighthouse is a disused 19th century lighthouse on the Isle of Portland, Dorset, southern England. It is located at Branscombe Hill on the west side of Portland, overlooking Portland Bill. The lighthouse is Grade II Listed.

Minerve (Q185/P26) was the lead ship of the Minerve-class submarines of the French Navy. Commissioned in 1936, during World War II she served in the Free French Naval Forces, and was wrecked in late 1945.

The Old Lower Lighthouse is a disused 19th century lighthouse on the Isle of Portland, Dorset, southern England. It is located along the eastern side of Portland Bill. The lighthouse, including its boundary walls and coastguard house, became Grade II Listed in September 1978.Working alongside the Old Higher Lighthouse from 1716, the lower lighthouse has subsequently been rebuilt twice, once in 1789 (when it became the first working lighthouse to have its light intensified by lenses and again in 1869. The lighthouse seen today was built in 1869 and has been the home of the Portland Bird Observatory since 1961.

Wallsend Cove is a cove, located on the Isle of Portland, Dorset, England; part of the Jurassic Coast. It is found on the west side of Portland, further south from Mutton Cove, and situated between Southwell Business Park and Portland Bill. The cliff tops above the cove are part of the South West Coast Path. The cove's cliffs are often used by rock climbers, and are known to be some of the biggest and best on Portland for climbing. Although the surrounding area of the cove features empty landscape, the limestone habitat is internationally important as it is home to many rare plants and insects.

Cave Hole is a large cave on the south east side of the Isle of Portland, a large peninsular in Dorset, England. It has a blowhole and a wooden crane, known as Broad Ope Crane on the cliff top. It is 1⁄2 mile (800 m) north-east of Portland Bill, has an interior measuring 50 feet (15 m) square and 21 feet (6.4 m) high. Cave Hole was earlier known as Keeve's Hole and regularly featured in recorded history and wider lore of smuggling. It is made up of a series of caves with steep roof sections, tunnels and ledges, and represents the first stage in cave collapse. The cave and its surrounding area is frequently used for deep-water soloing. The cave's blowhole, which stretches far into the solid rock, was formed when the roof of the cave was broken through to the surface. For the protection of people looking down into the cave, an iron grill has been installed across it. Whenever a powerful easterly gale occurs, the sea shoots up through the fissures.Various small craft have been driven into the cave by east and south easterly gales, the largest of which was a 40-ton vessel from Cowes in 1780. Frank and Ann Davison were shipwrecked at the cave in 1949. The pair had set sail for the West Indies. Frank drowned but Ann managed to scramble ashore. A local tale has long reputed that the cave is home to Roy Dog - a black dog, "as high as man, with large fiery eyes, one green, one red". It is said that the creature emerges from the watery depths to seize any traveller passing by Cave Hole and drags them down into his dark watery domain.
