That pointy bit is Brean Down Fort, not urbex material for you as it's well managed by National Trust but very worth a day out if you're in this part of the world
thanks @livinguktaiwan have last year reclaimed my life and my ex has moved back home to Truro,( there is a god!!!) so have over the years spent quite sometime in mainly Cornwall.
