Three unused 19th Century resevoirs in Hartlepool have been put up for sale.
The sites at Hurworth Burn, Crookfoot and Hart were used to supply the old docks in Hartlepool with water, which was then turned into steam to power the old shipbuilding industries.
David Quayle from H&H Land and Property, which is selling the land, said it had "no idea" what price to expect for the sites.
