Coastguard Tower.

You have seen this building before, but perhaps not in this light.  I was out early to take photos as the day was forecast to be wild, wet and windy.  Fortunately that hasn't materialise yet.  Scotland stands out as do Robin Rigg turbines looking white (which they are) in this light.  Depending on the light their colour 'changes.'
This coastguard lookout is now one of the starts/finishes of the C2C  long distance path.
