The Portland Royal Naval Hospital was a naval hospital on the Isle of Portland, Dorset, England. Serving HMNB Portland at Portland Harbour, the hospital is located close to Castletown. Discounting earlier, temporary incarnations of the hospital, the permanent naval hospital was built at the beginning of the 20th century. It closed in 1957, when it was handed over to the National Health Service, which still runs the hospital as NHS Portland Community Hospital.

Castletown is a small village in Underhill on the Isle of Portland in Dorset. It is located close to Fortuneswell, on the shores of Portland Harbour, and includes a sandy beach, as well as one of Portland's notable highlights; Portland Castle, while the Weymouth and Portland National Sailing Academy is also located nearby. As with the rest of Portland's villages and settlements, Castletown has been designated as a conservation area, as it is a place of special architectural and historic interest. Underhill, incorporating Castletown and other settlements became designated in 1976 with boundary extensions in 1997 and 2000.

Underhill is the name given to the area of very steep land, at the northern end of the Isle of Portland in Dorset, England, which contains the villages of Chiswell, Castletown and Fortuneswell. The remaining part of the island is known as Tophill. The geology of Underhill is different from Tophill; Underhill lies on a steep escarpment composed of Portland Sand, lying above a thicker layer of Kimmeridge Clay, which extends to Chesil Beach and Portland Harbour. This Kimmeridge Clay has resulted in a series of landslides, forming West Weares and East Weares.

Royal Manor Theatre is a theatre located in Fortuneswell, Isle of Portland, Dorset, England. Formerly a Methodist chapel, the building was later converted into the Royal Manor Theatre, which opened in 1978.

St. John's Church (also known as St John the Baptist Church) is an Anglican Church of England church in Fortuneswell, on the Isle of Portland, Dorset. It was built between 1838–40 and has been a Listed Grade II building since January 1951. The churchyard walls, gate piers, railings, and steps of St. John's Church, dating from 1839–40, became Grade II Listed in September 1978. At this same time, two headstone monuments, about 5 metres north east from the west tower of the church became Grade II Listed.Designed by Edward Mondey or Charles Wallis, the church cost £2,315. Built of Portland stone, the church has a Gothic design in Commissioners' Early English style. It has also been described as Norman in its architecture.The church remains active, as part of the Portland Parish - a host of three churches; St John's Church (St John the Baptist), All Saints Church and the Avalanche Memorial Church (St Andrew's Church).

Portland Castle is an artillery fort constructed by Henry VIII on the Isle of Portland, Dorset, between 1539 and 1541. It formed part of the King's Device programme to protect against invasion from France and the Holy Roman Empire, and defended the Portland Roads anchorage. The fan-shaped castle was built from Portland stone, with a curved central tower and a gun battery, flanked by two angular wings. Shortly after its construction it was armed with eleven artillery pieces, intended for use against enemy shipping, operating in partnership with its sister castle of Sandsfoot on the other side of the anchorage. During the English Civil War, Portland was taken by the Royalist supporters of King Charles I, and then survived two sieges before finally surrendering to Parliament in 1646. Portland continued in use as a fort until the end of the Napoleonic Wars in 1815, when it was converted into a private house. Fresh concerns over invasion led to the War Office taking it over once again in 1869, but the castle was not rearmed and was instead formed accommodation for more modern neighbouring fortifications. During the First and Second World Wars it was used as offices, accommodation and as an ordnance store. In 1949, the War Office relinquished control, and in 1955 it was opened to the public by the state. In the 21st century it is managed by English Heritage and operated as a tourist attraction, receiving 22,207 visitors in 2010. Historic England consider the castle to form "one of the best preserved and best known examples" of King Henry's forts.

There is a children's play area, tennis courts and a bowling green managed by the Portland Victoria Bowls Club.

The Portland Mulberry Harbour Phoenix Units are two reinforced concrete caissons, built as part of the artificial Mulberry harbours that were assembled as part of the follow-up to the Normandy landings during World War II. Out of a total of 148 produced units, two units still remain at the Isle of Portland, in Dorset, southern England. They are located at Portland Harbour, close to Queen's Pier. The two units became Grade II Listed in 1993.

The Phoenix breakwaters were a set of reinforced concrete caissons built as part of the artificial Mulberry harbours that were assembled as part of the preparations for the Normandy landings during World War II. They were constructed by civil engineering contractors around the coast of Britain. They were collected at Dungeness and Selsey, and then towed by tugboats across the English Channel and sunk to form the Mulberry harbour breakwaters replacing the initial "Gooseberry" block ships. Caissons were added in the autumn of 1944 to reinforce the existing structure to cope with the harbour continuing in use longer than planned. Several Phoenix breakwaters still exist in Britain: two are part of the harbour off Castletown at Portland Harbour in Dorset, and two can be dived in less than 10 metres of water off Pagham in West Sussex. There is also a smaller Phoenix Caisson (type C) in Langstone Harbour in Hampshire.A wrecked Phoenix breakwater is also to be seen, broken in two, in the Thames estuary off Shoeburyness in Essex. It broke while being towed from Harwich in June 1944. To avoid it causing a hazard to shipping in the Thames estuary, it was beached on the mud on the northern edge of the Thames dredged shipping channel. It is about a mile from the beach. It is not quite covered at high tide, but it is topped by a beacon to warn shipping of its presence. Several Phoenix breakwaters were used in the Netherlands to plug gaps in the dykes, four of them for a dyke at Ouwerkerk after the North Sea Flood of 1 February 1953. These four have now been converted into a museum for the floods called the Watersnoodmuseum. One can walk through the four caissons. Two of the Phoenix breakwaters were sold to Sweden in 1949, initially towed to Frihamnen port in Stockholm and moved on 20 September 1956 to the newly-built heat and power plant in Hässelby where they remain as of 2021.

Royal Naval Cemetery (once known as Naval and Military Cemetery) is a cemetery on the Isle of Portland, Dorset, England. The site overlooks Portland Harbour, and is found below the main entrance to the Verne Citadel (HM Prison The Verne). As the name suggests, the graveyard holds deceased servicemen and officers of Portland's Royal Navy which was stationed at the island until 1995. The cemetery holds 140 identified casualties in total to date, and is owned by the Ministry of Defence. The cemetery was first laid out during the 19th century. With the establishment of a naval base at Portland Harbour, and the Verne Citadel fortification, a number of fatalities began to occur. Burials of World War I (1914–1918) total 65, where 5 remain unidentified. The majority of World War II (1939–1945) graves are together in the Church of England section, near the Cross of Sacrifice. Of the buried, 10 are unidentified, whilst there are burials for 1 Norwegian Merchant Navy seaman and 12 German airmen. The cemetery remains well looked after to date and features a small amount of newer burials of recently deceased servicemen.

The Captain's House is a large detached house located at the bottom of Mallams, near the villages of Chiswell and Fortuneswell, on the Isle of Portland, Dorset, England. The house, together with the attached wall to the south east, has been a Grade II listed building since September 1978. It is not to be confused with another Captain's House on Portland, in Castletown, a large detached house, adjoining Portland Castle.The earliest parts of the Captain's House have been dated to the 17th century. It was formerly one of the grandest in the Underhill area, but later became a ruin in the late 19th century following the death of the last occupant John Comben Lano in 1866. It remained in the same state for over one hundred years until work began in 1995 on the restoration of the house, which was completed in 1998.

Conjurers Lodge is a former Methodist chapel and workshop on the Isle of Portland, Dorset, England. It is located on the corner of Clements Lane within the village of Chiswell. Established in 1816, the chapel was in use for a decade. The lodge has been Grade II Listed since 1993 and is described as a "rare surviving example of its kind" on the island.Following rumours of local Methodists believing in witchcraft, investigations by Rev. Francis Derry led to 50 members of Portland's society being expelled in 1816. This group then established a chapel on the upper floor of a workshop in Chiswell, which gained the name Conjurers Lodge. It remained in use for ten years until 1826, when the Methodist society was united once again. Portland Joinery later used the building as a workshop from 1973 to 2003.
