Fort Hubberston

Fort Hubberston is a Grade II* listed structure built with rock-faced blue limestone, known for its remarkable precision. The roofs are brick-vaulted and of exceptional quality. The fort consists of two major elements separated by a significant area of rough ground, both enclosed by surrounding walls. To the north, the defensible barracks are parabola-shaped to the northeast, facing a deep defensible ditch, and feature a large southwest cross-building, which together create a roughly triangular courtyard. The outer walls are sheer, topped with a flat parapet and equipped with 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 thirteen flat-roofed windows, cambered-headed and arched doorways. The parabola is designed with a series of giant two-storey arches, numbering around twenty, which are brick-vaulted and were once floored with rendered brick fronts within each arch. The outer four bays on each side are wider than the others, with flat roofs and brick chimneys positioned behind the high parapet.

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