This Castle is the "Tower of Refuge" in Douglas Bay on the Isle of Man taken in the very dull light of a rainy morning. It was built in1832 on the rocky outcrop where ships had been wrecked and was stocked with food etc. for the unfortunates to wait for rescue.
NOTE - I will be posting this text on all my photos until I know it is "safe" . As Google have now all but destroyed G+, with the"new Google+, the MOMENT that they remove the infinitely scrolling "notification" page ( this one https://plus.google.com/notifications/all ) then I am OUTTA here and will stop giving them FREE content.
PLEASE send feedback to Google asking them to keep that page, as it is the ONLY sensible way to see the hundreds of notifications I get. I have managed once before to get it restored.. but...
They also recently KILLED the old photo page where I organised my albums - so this MAY be the last photo I post to Google
