Fort Hubberston

Fort Hubberston is a Grade II* listed structure built with rock-faced blue limestone, known for its precise construction. The roofs are brick-vaulted and of exceptional quality. The site consists of two main elements separated by a large area of rough ground, both enclosed by walls. To the north, the defensible barracks are shaped like a parabola to the northeast, facing a deep defensive ditch, with a large southwest cross-building that creates a roughly triangular courtyard. The outer walls are sheer, featuring a flat parapet, rifle slits, small square windows, and a cambered-headed northern entry inscribed 'Fort Hubberstone' and 'VR 1863'. The feet of the parabola extend beyond the cross range to form covering angle bastions.

Inside the defensible barracks, the cross-range has a two-storey facade with 13 flat-roofed windows, cambered-headed and arched doorways. The parabola is defined by a series of about 20 giant two-storey arches, which are brick-vaulted and were originally floored with rendered brick fronts within each arch. The outer four bays on each side are wider than the others, and the flat roofs are topped with brick chimneys behind the high parapet.

From the main northern entry, the outer wall extends impressively to the southwest lower battery, which features a massive low-set curved facade with a bull-nosed cornice and a heavy parapet. There is an arched doorway leading to the gun emplacements at the northern end, followed by a sea-facing range of 12 large square granite-framed gun openings, most of which have been infilled, but the masonry remains in superb condition. Inside, there is a deep-sunk passage with a row of granite corbels, a stone rear retaining wall that incorporates tunnels leading back into the hillside, and a brick front opposite the groin-vaulted gun chambers. Further fortifications to the east, which link back to the southeast corner of the barracks, are overgrown and difficult to access.
