Hexagonal Airfield defence pillbox

Several hexagonal pillboxes can be seen close to the perimeter of RAF Detling in Kent, the example in the pictures is probably the most well known and visible beside the A249 on the Kent County showground. Note this pillbox is six sided with central open well and protected side entrance.
