Clearance site of Rotherham Power Station (pictured Munford 2000, 140). This site was demolished between 1973 and 1985. First power station on site opened 1920 (ibid, 133). The boundaries of this polygon are formed by the River Don and the Rotherham Cut of the South Yorkshire Navigation. The canal frontage of the polygon was the site of the Phoenix Forge of Sandford and Yates built c.1820 (Munford 2003, 60) These buildings represented expansion of the business from its beginnings at the 'New Foundry' to the immediate south. By the 1880s the business (now Yates and Heywood) had outgrown these buildings and moved to the Effingham works on Thames Street. On the 1891 map the canal frontage buildings are shown as disused.
