Saltpans at Croscannonby, on the Solway Firth, Cumbria.
A 17th century salt works, built be the Senhouses of Netherhall, and probably only operational from 1650 to 1736. As a child, my family had a caravan on the opposite side of the road and I used to play in the saltpans and ruined buildings on the site. The works were largely demolished in 1970.
