Fort Nelson is one of five Portsdown Forts. Built as a result of the 1859 Royal Commission by Lord Palmerston to prevent a French land attack on the Portsmouth dockyard only 8 kilometres away, because the older Hilsea Lines at the bottom of the ridge were considered insufficient. A series of 6 forts were built along the 7 miles (10 km) of the ridge. From west to east they are forts Fareham, Wallington, Nelson, Southwick, Widley and Purbrook. The line was finished off at the eastern end with Crookhorn Redoubt and Farlington Redoubt. A garrison of around 200 volunteers accompanied by regular army officers would have staffed the fort in time of war. Construction was protracted and Fort Nelson was not fully armed until the 1890s.[4] The fort was disarmed in 1907 and then used for accommodation. In 1938, it was converted to an area anti-aircraft ammunition store; ten large magazines were built on the parade ground. Fort Nelson was abandoned in the 1950s.
Royal Armouries
In 1979, after years of neglect and vandalism, it was sold to Hampshire County Council[5] for £50,000. The Council, with assistance of volunteers from the Palmerston Forts Society, restored it at a cost of £3–4 million, and it opened to the public in 1994, becoming part of the Royal Armouries in 1995. It houses their collection of artillery, including:
The 'Boxted Bombard', an English wrought iron cannon from around 1450, which was powerful enough to fire a 60 kg granite ball
The 'Dardanelles Gun', an Ottoman bronze cannon from 1464 which was powerful enough to fire stone balls with a diameter of 63 cm[6]
The fort covers around 19 acres (77,000 m2) and is open all year round, with no charges except for some special events. Live firing demonstrations are held every day, costumed guides, video presentations, and visitors are able to explore the tunnels that run below the fort connecting the magazines with gun emplacements. There are displays demonstrating the living and working conditions of the soldiers who defended the fort, and views over Portsmouth, the Solent, Hayling Island and Gosport, with the Isle of Wight beyond.
