Sailing at the 2012 Summer Olympics

The Weymouth and Portland National Sailing Academy is a centre for the sport of sailing on the Isle of Portland, Dorset, on the south coast of England. The academy building is located in Osprey Quay on the northern tip of the island, and the waters of Portland Harbour and Weymouth Bay, adjacent to the site, are the main areas used for sailing. Local, national and international sailing events have been held at the site since it was opened in 2000, and in 2005 WPNSA was selected to host the sailing events at the 2012 Olympic and Paralympic Games.

Weymouth and Portland was a local government district and borough in Dorset, England. It consisted of the resort of Weymouth and the Isle of Portland, and includes the areas of Wyke Regis, Preston, Melcombe Regis, Upwey, Broadwey, Southill, Nottington, Westham, Radipole, Chiswell, Castletown, Fortuneswell, Weston, Southwell and Easton; the latter six being on the Isle of Portland. In Portland Harbour is the Weymouth and Portland National Sailing Academy, where the sailing events at the 2012 Olympics took place. The main reason that the resort was chosen to be an Olympic venue was that the Sailing Academy had only recently been built, so no new venue would need to be provided. Weymouth and Portland's waters have also been credited by the Royal Yachting Association as the best in Northern Europe.Weymouth and Portland have been twinned with the town of Holzwickede in North Rhine-Westphalia, Germany, since 1986, and the French town of Louviers, in the department of Eure in Normandy, since 1959.

South Dorset is a constituency represented in the House of Commons of the UK Parliament since 2010 by Richard Drax, a Conservative. The constituency was created as a consequence of the Redistribution of Seats Act 1885, although the area covered has changed since then.

RNAS Portland was an air station of the Royal Navy from 1917. The site was first built in 1917 as HMS Sarepta within the confines of Portland Harbour as a seaplane base; the aircraft operating from the base's slipways. In 1959 it became RNAS Portland (HMS Osprey)

RNAS Portland (ICAO: EGDP) was an air station of the Royal Navy, situated at the Isle of Portland, Dorset, England. It was established in 1917 on the western edge of Portland Harbour as HMS Sarepta. From 1959 the station shared the name HMS Osprey, the anti-submarine establishment based at Portland, with helicopters used for research and development in anti-submarine techniques. RNAS Portland remained operational until 1999.

Portland was a railway station on the Portland Branch Railway in the south of the English county of Dorset. The station opened with the Easton and Church Hope Railway, one of the constituent parts of a complex line, on 16 October 1865. The station was moved to a new site on the opening of the extension to Easton on 1 September 1902.After this, the old station was used as a goods station and depot. The extension was technically a separate railway, the Easton and Church Hope, although the branch was operated as one line throughout. The second Portland station had multiple platforms with canopies for the large staff of the Admiralty establishments around it. The station closed to passengers in 1952, although regular freight kept the line in use until 1965. The platforms and canopies survived until the mid-1970s when the site was absorbed by the base and demolished.

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.

Victoria Square is a public square on the Isle of Portland, Dorset, England. Developed in the 19th century, it is situated at the entrance to Portland, close to Chesil Beach, Osprey Quay, and the small fishing village of Chiswell.

Chiswell , sometimes , is a small village at the southern end of Chesil Beach, in Underhill, on the Isle of Portland in Dorset. It is the oldest settlement on the island, having formerly been known as Chesilton. The small bay at Chiswell is called Chesil Cove, and the beach promenade and sea wall which form Chiswell's coastal defences are a prominent feature. The village occupies much of the flat land close to sea level adjacent to the beach, and is distinguished from the adjoining village of Fortuneswell which occupies the steeper hills and streets above. At the northern entrance to the village is the 19th-century development of Victoria Square, which forms a roundabout on the main A354 road onto the island. As with the other villages and settlements on Portland, Chiswell was designated as a conservation area as part of Underhill in 1976, as it is a place of special architectural and historic interest. The village has been maintained by the Chiswell Community Trust since 2003.

It closed in 1957, when it was handed over to the National Health Service, which still runs the hospital as NHS Portland Community Hospital.
