Royal Hospital Haslar

The Royal Navy Submarine Museum at Gosport is a maritime museum tracing the international history of submarine development from the age of Alexander the Great to the present day, and particularly the history of the Royal Navy Submarine Service from the navy's first submarine, Holland 1, to the nuclear-powered Vanguard-class submarines. The museum is located close to the former shore establishment HMS Dolphin, the home of the Royal Navy Submarine Service from 1904 until 1999.

HMS Alliance (P417/S67) is a Royal Navy A-class, Amphion-class or Acheron-class submarine, laid down towards the end of the Second World War and completed in 1947. The submarine is the only surviving example of the class, having been a memorial and museum ship since 1981. The Amphion-class submarines were designed for use in the Far East, where the size of the Pacific Ocean made long-range, high surface speed and relative comfort for the crew important features to allow for much larger patrol areas and longer periods at sea than British submarines operating in the Atlantic or Mediterranean had to contend with. Alliance was one of the seven A-class boats completed with a snort mast - the other boats all had masts fitted by 1949.

In September 2022, the Guardian reported that Haslar immigration removal centre would reopen in late 2023.

Holy Trinity is a Church of England church in the Anglo-Catholic tradition in Gosport, Hampshire, within the Anglican Diocese of Portsmouth. It is the civic church for the Gosport deanery and hosts commemorative events and the annual mayor's carol service.

Haslar is on the south coast of England, at the southern tip of Alverstoke, on the Gosport peninsula, Hampshire. It takes its name from the Old English hæsel-ōra, meaning "hazel-landing place". It may have been named after a bank of hazel strewn on marshy grounds around Haslar Creek to make it passable and habitable in old times, or merely because hazel grew there.

Fort Blockhouse is a former military establishment in Gosport, Hampshire, England, and the final version of a complicated site. At its greatest extent in the 19th century, the structure was part of a set of fortifications which encircled much of Gosport. It is surrounded on three sides by water and provides the best view of the entrance to Portsmouth Harbour. It is unique in that it was built over five centuries from its original construction as a blockhouse in 1431 to the final addition of submarine base structures in the mid-1960s. Coastal fortification was abolished nationally in 1956, and the fort has not been used in a military capacity since 2021.The MoD plans to dispose of the site in 2025.

Royal Clarence Yard in Gosport, Hampshire, England was established in 1828 as one of the Royal Navy's two principal, purpose-built, provincial victualling establishments (the other being Royal William Yard in Plymouth, Devon). It was designed by George Ledwell Taylor, Civil Architect to the Navy Board and named after the then Duke of Clarence (later William IV, King of England). The new victualling yard was developed on approximately 20 hectares of land, some of which was already in use as a brewing establishment at Weevil on the west shore of Portsmouth Harbour, to the north of Gosport. Queen Victoria regularly used Royal Clarence Yard as her disembarkation point for the short journey across the Solent to her house at Osborne in the Isle of Wight, travelling from Gosport Station on the single track line extension which had been opened in 1844 principally for this purpose.Between the establishment of the Yard and its eventual decommissioning in the early 1990s, Royal Clarence Yard supplied provisions to the Royal Navy in all the major conflicts of this period.In 1995, the Ministry of Defence (MoD) declared 16.26 hectares of Royal Clarence Yard surplus to requirements and released it to Gosport Borough Council. Berkeley Homes bid for the land in 1998 and was granted planning permission for a mixed use development in 2001. The south-eastern part of the Yard (approx 3,74 hectares), which includes the Oil and Pipelines Agency access to the Gosport Oil Fuel Depot, was retained by the MoD for operational reasons. In 2014, the Defence Infrastructure Organisation announced plans to release most of the rest of the retained land at Royal Clarence Yard to Gosport Borough Council.
