The island of Ailsa Craig is a prominent feature visible from nearly everywhere along the Airshire coast. The dome shaped island is a volcanic plug left behind by an extinct volcano in the Irish Sea and is nick named Paddy’s milestone because is is halfway between Glasgow and Belfast, as the crow flies.
If you like solitude, the 220 acre island with a ruined castle, a small cottage, a lighthouse and a granite quarry is for sale for a mere £1.5m.
