Fort Albert

Fort Albert

A former artillery fort built in 1854 with an attached torpedo house of 1886, subsequently altered in the 1940s and converted to residential use in the 1970s-80s. The fort stands on an artificial island to defend the western approach to Portsmouth, opposite Hurst Castle.

The original structure consists of brick foundations and superstructure with a granite base. A broad irregular chevron in plan pointing west, it rises three storeys and is surmounted by a warhead. Above this sits a lift shaft of the 1970s serving a smaller fourth storey of flat-roofed buildings constructed in the 1940s for anti-aircraft purposes, topped by two direction towers. A prominent 1980s addition with slate false pitches is attached to the north of the northern turret. The single-storey torpedo house with a mass concrete roof shallowly pitched against the fort masks the eastern return at the north end; it covers a brick half-vault. The winding room beyond is flat-roofed.

The seaward face is pierced by cambered-headed gunports and musket loops, now glazed. Some retain granite sills with sunk margins. All external surfaces are now rendered except for the western face. Landward, where rendering conceals detail, only two storeys are visible. The southern end presents one bay with tripartite windows on each floor, followed by two bays of simple openings taller than those to seaward, then a gate-tower with small windows above the plain first floor entrance. A lift shaft in line with the gate-tower echoes similar idiom. The wallhead features a covered gallery with small musket loops and sloping crown terminating in bartisans. The torpedo house, rendered over brick, displays large modern sliding doors marking the storage area on its northern side, and a small projection showing the outline of the arch through which torpedoes were launched. The northern facade presents two bays with ground floor ports now blocked. The granite base shows a descending sequence of housings for sleepers of the Brennan torpedo launch rail, now dismantled. A cantilevered former searchlight position of the 1940s crowns the wallhead. The western facade comprises seven bays with ground floor ports blocked. The southern facade has two bays.

The interior was originally divided into seven brick compartments on each floor but has been substantially altered for residential conversion. Gunport splays show inner reveals in two stages. The torpedo house incorporates a semi-vaulted recess cut from the fort wall foot with rods inset into the vaulting; the passage to the winding room contains rectangular sinkings in its walls—all presumably connected to operation of the wire-guided Brennan torpedo. The structure stands over the original moat, which allowed construction of subterranean chambers that may survive.

The fort was intended to house 29 guns in four tiers and represented among the last gun-towers constructed in England, rapidly rendered obsolete by advances in gunnery. In 1886 it was selected as a UK location for the Brennan wire-guided torpedo, which possessed sufficient range to close the Solent strait. This installation was dismantled in 1906. Small guns only were subsequently mounted, and the fort finally closed in 1957. It remains important as a late example of its type and for its association with the Brennan torpedo installation.
