Gosport (ˈɡɒspɔərt ) is a town and non-metropolitan borough, on the south coast of Hampshire, South East England. At the 2021 Census, its population was 81,952. Gosport is situated on a peninsula on the western side of Portsmouth Harbour, opposite the city of Portsmouth, to which it is linked by the Gosport Ferry. Gosport lies south-east of Fareham, to which it is linked by a Bus Rapid Transit route and the A32. Until the last quarter of the 20th century, Gosport was a major naval town associated with the defence and supply infrastructure of His Majesty's Naval Base (HMNB) Portsmouth. As such over the years extensive fortifications were created.
Gosport is still home to and a Naval Armament Supply Facility, as well as a Helicopter Repair base. The Town area of the Borough, including Newtown, consists of the town centre, Stoke Road shopping area, Walpole Park, Royal Clarence Yard and three modern marinas: Royal Clarence, Gosport Marina and Haslar Marina. As part of the Renaissance of Portsmouth Harbour Millennium project, a large sundial, known as the Millennium Timespace, was installed on the harbour front in 2000.
Though there are multiple theories which point towards the etymology of Gosport, it is widely purported to derive its name from "goose". An alternative etymology of "gorse" (from the bushes growing on local heathland) is not supported by the regional name for the plant, "furze". A third theory, claiming a derivation from "God's Port" is believed to be a 19th-century invention. This is, however, the slogan of Gosport as demonstrated on its emblem.
The Rowner area of the peninsula was settled by the Anglo-Saxons, and is mentioned in the Anglo Saxon Chronicle as Rughenor ("rough bank or slope"). Both Rowner and Alverstoke, the name coming from the point where the River Alver entered the Solent at Stokes Bay, were included in the Domesday Book. Rowner was the earliest known settlement of the peninsula, with many Mesolithic finds and a hunting camp being found, and tumuli on the peninsula investigated.
