Pillbox Square Type at Grid Ref. SK 62300 35984

This is a Second World War pillbox built in 1941, part of the airfield defenses for Tollerton Airfield. It is one of 18 pillboxes that remain around the edge of the airfield.

The pillbox is constructed of brick with concrete lintels and features a flat concrete roof. Although described as 'square', it has chamfered corners, giving it an octagonal appearance. It is surrounded by an earthen bank that rises up to 0.5 meters high and 0.5 meters wide. There is an entrance on the south side, which is protected by a pentice, and there are embrasures facing the airfield. These embrasures have stepped concrete surfaces that would have served as bullet stops. The walls of the pillbox are over 1 meter thick.

No internal inspection was conducted due to tree growth making access difficult, but it was noted that Turnbull mountings are still visible within the embrasures.
