No Place Like Home

Castle Sinclair-Girnigoe, on Noss Head, provides a home for fulmars. 

As far as ruined castles go, it's pretty good - a spectacular location and enough ruins to be interesting.  On a clear day, which this was, we could see Duncansby Head lighthouse.  If we'd had the binoculars, we could have seen Ronaldsay, part of Orkney.
