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.

Point Battery (which is also known by its earlier name, Eighteen Gun Battery) is a former gun emplacement on Portsmouth Point in Hampshire. Part of the fortifications of Portsmouth, it was built alongside an earlier defensive structure (the 15th-century Round Tower) to help defend Portsmouth Harbour in the event of an attack. Fort Blockhouse on the other side of the harbour entrance was rebuilt at around the same time as part of the same scheme. In the mid-19th century the battery was enlarged and Point Barracks were built alongside, to house the artillery troops responsible for manning the defences. Point Battery, along with the barracks and other associated structures, is a Grade I listed building.
