After many many visits I was stunned to find the R1 bunker at the former RAF Bempton has been filled and sealed. Not really much left to see here now but a few empty Type 80 radar plinths and a few scattered WW2 Chain Home buildings.
The emergency exit and vent have also been filled in and welded.

Receiver Block for Mark 1 Type 80 Radar
This is where you went down to the underworld, it's now filled with the roof and has these 10 ton concrete blocks over it.
Remains of the guardhouse / bungalow
Welded escape hatch and vent.
Thi sis what remains of Project Winkle, a still classified over the horizon radar prototype based here in the 1970s
