Tantallon Castle from Seacliff Harbour.
A ruined castle high on a cliff overlooking the Firth of Forth east of Edinburgh, Scotland. The viewpoint is Seacliff - a private beach (deserted on a sunny January day).
An amazing harbour, hewn straight out of the sandstone rocks is invisible from the sea and land unless you are very close. Apparantly it’s the smallest harbour in the UK and still used by lobster fishermen.
