Some nice remains in this area, two lozenge pillboxes and an engine room. What is special about the pillboxes is that both still have all their wooden weapons shelves in place - its extremely rare to find these still in situ. In this case now doubt helped by the fact that the entrances to the pillboxes are bricked up! Also in the fields are a number of concrete posts which may have been obstacles to prevent gliders/troop carrying planes from landing. Not sure what the generator in the engine room would have powered - what ever it was has since disappeared over the cliff.
