Terraced housing built on the site of the Milton Ironworks which was opened between 1799 and 1802 (Jones 1995, 80) by Darwin and Co. on land that was part of Earl Fitzwilliam's estate. The ironworks was the major customer for the nearby Elsecar Old Colliery and took 77% of its coal (Medlicott 1987, 111). The exact position of the colliery is uncertain as it had been replaced by Elsecar New Colliery by first edition (1855) maps. Earl Fitzwilliam took direct control of the ironworks in 1827 when the firm went bankrupt. In 1849 when both Elsecar and Milton Ironworks were leased to the Staffordshire firm of W.H. and G. Dawes. The Ironworks had closed by 1927. (www.a2a.org.uk [accessed 23/08/07] Sheffield Archives Ref: SY/738/Z - Administrative History). Previously this land would have been part of the medieval town field. There is no legibility of the enclosed landscape or ironworks. Polygon also included the Hoyland corn mill which was still marked as such on 1855 maps. After thing point it probably fell out of use. The origins of the mill are unknown.
