I think you have solved the mystery of Castlewi'Rock in Windmill Street, Saltcoats. When I first saw the picture my thoughts were that it housed the fabled Windmill which was opposite the end of Sidney Street just about where the Pavilion Theatre / Bowling Alley was built. But then the puzzle of my wedding party venue at the Castlewirock came to mind. Standing at Windmill street it was in the past possible to see Ardrossan Castle high on its hill, but hardly seemed significant enough to name your business premises after it. I used to think maybe the original Windmill ( which I believe was used to pump seawater up to the 'cots' and heated by burning seaweed under the pans) was built like a Castle Tower but if not that maybe it was a Castle Tower like Montfode or Portincross. The picture of the harbour is not as accurate as the photos of the harbour show the nearer building as larger ( now demolished) and the other was the Customs House, still there.
