Lighthouse on Ailsa Craig - now solar powered and unmanned. The white section appears to be maintained and is very secure; the grey buildings are now in ruins. Compare with NX0299 : Ailsa Craig Lighthouse from 1988.
My Photo! I am commenting following several general comments regarding square baggers. I am unashamed to have taken this from 15km away. Had I been "close up" the view of NX0299 would have been perhaps more detailed BUT, I maintain less recognisable for this quadrant of the island.
