Pillbox Type Lozenge.
Note stretched hexagonal plan with central anti-ricochet wall.
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. 176 examples of this type remain extant. (wikipedia)
After 70 years of high tides combined with soft clay cliffs these pill boxes have ended up on the beach
These 2 pill boxes are on the beach at "The Bay" Near Filey at the site of the old Butlins camp. These have been on the beach for at least the last 40 years, as i remember sitting behind these when my kids were young.
