It's a horse ..

.. no it's a dog; no it's a unicorn.  It's actually the Red Castle at Lunan Bay, built in the 12th Century in defence against Viking invasions.  There isn't much left of the original structure today apart from a few crumbling walls, but it makes for a dramatic viewpoint of the entire Lunan Bay.  This is at the opposite end of the walk we were on yesterday, about 11km. The other extra blip is of seagulls that have nested on the Red Castle.
