A pair of Tett Turrets

A linked pair of Tett Turrets: small military structures set partially below ground, designed to provide a protected gun position for a single occupant, with a rotating cap section which allowed a 360 degree field of fire.

MATERIALS: pre-manufactured reinforced concrete turret mounted on brick walls.

PLAN: the turrets are arranged in what is believed to be a unique configuration, aligned north-south, and linked by a 12ft long narrow circular tunnel. A short branch tunnel, located at the centre of the linking tunnel extends westwards, and may have provided access to the turrets from a trench at the rear of the site.

EXTERIOR: the above-ground elements of the twin turrets are low rotating concrete truncated cones, each with a single gun embrasure and several spy holes or slits. The cones are mounted on ball-bearing races which allowed the turrets to be turned. The turret cones are set upon concrete slabs, supported upon rectangular brickwork enclosures. The southern enclosure has an opening in the south side wall.

INTERIOR: the turrets retain steel seat hangars for wooden seats, one of which is believed to survive (2016).
