Haslar is on the south coast of England, at the southern tip of Alverstoke, on the Gosport peninsula, Hampshire. It takes its name from Anglo-Saxon hæsel-ōra = "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.

Royal Haslar Hospital and Royal Naval Cemetery[edit]

Main article: Royal Hospital Haslar

The location consists principally of the Royal Hospital Haslar site (previously the Royal Naval Hospital Haslar). The site for Haslar hospital was bought in 1745; before that the land was Haslar Farm (though spelt Hasler Farm at the time) within the liberty of Alverstoke. The site was a slightly unusual location for a hospital because it was surrounded by the Gosport Creek, with no readily available access: such an area was chosen to prevent press-ganged sailors from absconding.

It was primarily to serve the hospital that the Haslar Royal Naval Cemetery was laid out. It contains (June 2014) Commonwealth war graves of 772 naval personnel of World War I (two of whom are unidentified), and 611 of World War II (36 unidentified), besides ten foreign sailors, and nine non-World War service burials. There is a mass grave of 42 officers and men of the submarine HMS L55, recovered from the Baltic Sea and repatriated in 1927, their names on a screen wall memorial.[1] Singer Chick Henderson, killed in a German flying bomb attack in Southsea, Hampshire in 1944, is buried here under rank and real name of Sub-Lieutenant Henderson Rowntree.[2]

Haslar Gunboat Yard and the Admiralty Experiment Works[edit]

Haslar Road: on the left is the Admiralty Experimental Works, on the right is Haslar Hospital; the chimney of the Gunboat Yard can be seen in the distance.

The strip of land between the hospital and the creek is occupied by the former Haslar Gunboat Yard, opened in 1856 to house the Royal Navy's coastal gunboats. A single patent slip was used to launch the boats into Haslar Creek, and to haul them out again on a cradle which ran on railway tracks; a locomotive-driven traverser then delivered the boat (still in its cradle) to its place in the row of cast iron boat sheds (ten of which still stand, parallel to the creek - at one time there were fifty in total). A small stationary steam engine mounted on the traverser platform drove an endless screw, which was then used to slide the boat back into its shed.

After a series of expansions and contractions, as gunboats went in and out of vogue in Naval circles, the Yard closed in 1906; but from 1912–1973 the site continued to provide storage and maintenance facilities for small vessels of various types.[3] During the Second World War it formed part of HMS Hornet, the adjacent Coastal Forces base; and when Hornet was decommissioned (in 1957) the Yard became an adjunct of the Admiralty Small Craft Experimental Works (see below).[4]

Haslar closed for good as a Boat Yard after the construction of a new Haslar Bridge, which prevented craft from sailing up the creek. The site is currently unused, but substantially intact; as well as the boat sheds, it contains a pair of guard houses flanking the gateway, several workshops and the former boiler house with its prominent chimney. (Steam from the boilers not only drove the winch, which hauled the boats up the slipway, but also powered the hospital laundry on the other side of the road.) The buildings are all of red brick, as is the surrounding perimeter wall, built with integrated watch towers to provide extra security.

Blue Plaque on the Admiralty Experimental Works

Alongside the Gunboat Yard, within the same compound, stands the Admiralty Experiment Works (later part of the Defence Research Agency and now owned by QuinetiQ). It contains a 540ft concrete water tank, built in 1884 to test different hull designs using wax models, and still in use today.[5] The tank was built for the Admiralty by Robert Edmund Froude in order to carry on the pioneering work of his father, William Froude, who had died in 1879. Over time, as the Gunboat Yard was reduced in size, the Experiment Works expanded to fill the available space.

Other features[edit]

Also here is Haslar Marina, which, along with Weymouth, East Cowes and Portland, is part of the Dean and Reddyhoff marina group. A large green lightship “Mary Mouse II” is permanently moored on the outside of the marina, by the harbour entrance. The Royal Navy Submarine Museum is found nearby. Haslar Immigration Removal Centre (formerly Haslar Prison) stands to the south-west of the former Hospital site.
