Kelham Island' is formed by the cutting off of this sliver of land by the head goit to the Kelham Wheel (see HSY 1774) and the medieval corn mill to the south east. This goit is culverted below Alma Street but originally continued through the 'Millsands' site rejoining the river Don just below Lady's Bridge. The main building within this polygon (now reused as Kelham Island Industrial Museum) was built by Sheffield Corporation as an electricity generating station for the city's tramway network in the 1890s (http://www.simt.co.uk/kelham/kelham-1.html) accessed 9/08/2005. The island has a long history of industrial use with earlier phases including the courtyard type Kelham Iron Works of 1829 (ibid) and the Russell Works (first depicted 1891), a crucible shop and stack of which survive 'in situ' (Bayliss 1995). Significant legibility of industrial buildings.
