Navigation towers and bunkers

Clear skies and sharp shadows on the concrete blocks of the coastal defence installations. I saw one of the towers I've been sketching this year, in a field with some pumpkins nearby. I think it's being used for water or power and was buzzing loudly. Also a casemate with carpet lined plywood doors, a tangle of ropes and a whole heap of tyres - dark and damp. One defence structure has a refurbished shell shrine in it, statues, music and green lights - photos to follow.
