The lozenge pillbox is found only in the North East of England. Lozenge pillboxes are an irregular hexagon in plan with the front and rear walls significantly longer than the others, this allows space for four forward-facing embrasures. The rear wall has two embrasures and an entrance. The four short walls each have a single embrasure. Internally, an anti-ricochet wall runs longitudinally. It was designed for infantry armed with rifles and/or light machine guns
