WFort Blockhouse is a 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 two respects. Firstly, it was built over five centuries from its original construction as a blockhouse in 1431 to the final addition of a submarine escape tower in 1953. Secondly, it is thought to be the oldest fortified position in the United Kingdom that is still in active military use though coastal fortification was abolished nationally in 1956, and it has been used only for medical and training purposes since 1999.
WFort Brockhurst is one of the Palmerston Forts, in Gosport, England and a Scheduled Ancient Monument. It is now an English Heritage property.
WBrowndown Battery, also referred to erroneously in some sources as Browndown Fort, is a former military coastal defence fortification and base on the Southern shoreline of England in the county of Hampshire. First erected in the mid-1840s, the battery was continuously modified until disarmed in 1905/6. It has been a Grade II Listed Building since 1983.
WCalshot Castle is an artillery fort constructed by Henry VIII on the Calshot Spit, Hampshire, England, between 1539 and 1540. It formed part of the King's Device programme to protect against invasion from France and the Holy Roman Empire and defend Southampton Water as it met the Solent. The castle had a keep at its centre, surrounded by a curtain wall and a moat. Initially heavily armed, it had a garrison of 16 men and as many as 36 artillery guns. The castle continued in use for many years, surviving the English Civil War intact and being extensively modernised in the 1770s. During the 19th century, Calshot Castle was used by the coastguard as a base for combating smuggling. In 1894, however, fresh fears of a French invasion led to it being brought back into use as an artillery fort: a large coastal battery was constructed alongside the older castle and a boom built across Southampton Water, controlled from the castle.
WPortsdown Hill is a long chalk ridge in Hampshire, England. The highest point of the hill lies within Fort Southwick at 131m above sea level. The ridge offers good views to the south over Portsmouth, the Solent, Hayling Island and Gosport, with the Isle of Wight beyond. The hill is on the mainland, just to the north of Ports Creek, which separates the mainland from Portsea Island, on which lies the main part of the city of Portsmouth, one of the United Kingdom's main naval bases. To the north lies the Forest of Bere, with the South Downs visible in the distance. Butser Hill can be seen on a clear day. The hill is formed from an inlier of chalk which has been brought to the surface by an east–west upfold of the local strata known as the Portsdown Anticline.
WFort Elson was one of the early Palmerston Forts, in Gosport, England, the northernmost polygonal land fort in the defence line to the west of Gosport. It was located on land immediately to the south of Elson Creek, to which it was connected by a sluice. Fort Elson was the most northerly fort in the line of five which formed part of the ‘Sea Front and Spithead Defences’, Inner Line, Land Front, Left Flank. This line of forts was later known as the Gomer-Elson Line or 'Gosport Advanced Line' This consisted of, from south to north, Fort Gomer, Fort Grange, Fort Rowner, Fort Brockhurst and Fort Elson. Work began on Fort Elson in 1855. The estimated cost of Fort Elson was £63,740 with the actual cost £61,180.
WFort Fareham is one of the Palmerston Forts, in Fareham, England. After the Gosport Advanced Line of Fort Brockhurst, Fort Elson, Fort Rowner, Fort Grange and Fort Gomer had been approved by the Royal Commission on the Defence of the United Kingdom a decision was made to build an outer line of three more forts two miles in advance of the Gosport Advanced Line. Of these three projected forts only Fort Fareham was built due to the need to cut costs. It acted as a hinge between the forts on Portsdown Hill and those of the Gosport Advanced Line, filling the gap at Fareham. It has been a Grade II Listed Building since 1976.
WFort Nelson, in the civil parish of Boarhunt in the English county of Hampshire, is one of five defensive forts built on the summit of Portsdown Hill in the 1860s, overlooking the important naval base of Portsmouth. It is now part of the Royal Armouries, housing their collection of artillery, and a Grade I Listed Building.

WWallington is a village in Hampshire, part of the borough of Fareham. It is situated between Portsmouth and Southampton near where the River Wallington enters Portsmouth Harbour.
WFort Gomer was one of the Palmerston Forts, in Gosport, England, the southernmost and first-built Polygonal fort in the defence line to the west of Gosport. It was located on land immediately to the west of the present Gomer Lane. Fort Gomer was the most southerly fort in the line of five which formed part of the ‘Sea Front and Spithead Defences’, Inner Line, Land Front, Left Flank. This line of forts was later known as the Gomer-Elson Line or 'Gosport Advanced Line' This consisted of, from south to north, Fort Gomer, Fort Grange, Fort Rowner, Fort Brockhurst and Fort Elson. An inscription above the main entrance through the barrack block read `Erected AD 1853’. The fort was almost complete before work began on Fort Elson in 1855. The estimated cost of Fort Gomer was £92,000 in 1869.
WFort Grange is one of the Palmerston Forts, in Gosport, England. After Gomer and Elson forts had been approved in 1852, further consideration led to a decision to fill the gap between them by three more forts, and Grange is the most southerly of the three. Work began in 1858 and it was completed in 1863.
WHurst Castle is an artillery fort established by Henry VIII on the Hurst Spit in Hampshire, England, between 1541 and 1544. It formed part of the king's Device Forts coastal protection programme against invasion from France and the Holy Roman Empire, and defended the western entrance to the Solent waterway. The early castle had a central keep and three bastions, and in 1547 was equipped with 26 guns. It was expensive to operate due to its size, but it formed one of the most powerful forts along the coast. During the English Civil War of the 1640s, Hurst was held by Parliament and was used briefly to detain King Charles I before his execution in 1649. It continued in use during the 18th century but fell into disrepair, the spit being frequented by smugglers.
WThe Palmerston Forts that encircle Portsmouth were built in response to the 1859 Royal Commission dealing with the perceived threat of a French invasion. The forts were intended to defend the Dockyard in Portsmouth. Construction was carried out by the Royal Engineers and civilian contractors. In addition to the newly constructed forts, extensive work was carried out on existing fortifications.
WNetley Castle is a former artillery fort constructed in either 1542 or 1544 by Henry VIII in the village of Netley, Hampshire. It formed part of the King's Device programme to protect against invasion from France and the Holy Roman Empire, and it defended Southampton Water near the Solent. The castle included a central, stone keep with two flanking gun platforms and was garrisoned by ten men. It was decommissioned during the English Civil War and by 1743 it was overgrown and in ruins. In the 19th century the property was gradually converted into a private house, being extended in a Gothic style, complete with octagonal towers. Between 1939 and 1998 it was used as a nursing home, until the high costs of maintenance led to its closure. Following an archaeological survey, it was then converted into nine residential flats. It is protected under UK law as a Grade II* listed building.
WThe fortifications of Portsmouth are extensive due to its strategic position on the English Channel and role as home to the Royal Navy. For this reason, Portsmouth was, by the 19th century, one of the most fortified cities in the world. The fortifications have evolved over the centuries in response to changes in tactics and technology and the area defended has increased. While the first defences focused on Portsmouth harbour, in step with the fortifications of Gosport, later defensive structures protected the whole of Portsea Island and an increasing distance inland. At the same time, the fortifications of Portsmouth and Gosport became part of the wider fortifications of the Solent. Old Portsmouth, on the southwest corner of Portsea Island, has been walled for much of its history.
WFort Rowner is one of the Palmerston Forts, in Gosport, England.
WSouthsea Castle, historically also known as Chaderton Castle, South Castle and Portsea Castle, is an artillery fort originally constructed by Henry VIII on Portsea Island, Hampshire, in 1544. It formed part of the King's Device programme to protect against invasion from France and the Holy Roman Empire, and defended the Solent and the eastern approach to Portsmouth. The castle had a square central keep, two rectangular gun platforms to the east and west, and two angled bastions to the front and rear, and was an early English example of the trace italienne-style of fortification popular on the Continent. The Cowdray engraving of the Battle of the Solent in 1545 depicted Henry VIII visiting the castle. Despite several serious fires, it remained in service and saw brief action at the start of the English Civil War in 1642 when it was stormed by Parliamentary forces.
WThe Stokes Bay Lines were part of the great Victorian fortification of Portsmouth Harbour under Lord Palmerston. In 1857 Major Jervois had proposed a complex system of moats (ditches), ramparts and batteries to close off the gap between the new fort at Fort Gomer, and the earlier fort at Fort Gilkicker, and Fort Monckton. This defensive moat was to become the ‘Stokes Bay Lines’.
WFort Widley is one of the forts built on top of Portsdown Hill between 1860 and 1868 on the recommendation of the Royal Commission on the Defence of the United Kingdom. It was designed, along with the other Palmerston Forts atop Portsdown, to protect Portsmouth from attack from the rear.
