Spike Island is an island in the estuary of the River Mersey, in North West England, flanked by the Sankey Canal. It is a reclaimed toxic waste site, considered a birthplace of the British chemical industry, and forms a part of Widnes in the Halton borough of Cheshire.
Its maze of abandoned chemical factories, rail lines, canal and industrial dockage, and industrial pollution, which had declined into a rust belt toxic wilderness, was reclaimed as woodland, wetlands and green space between 1975 and 1982. A surviving warehouse is now the home of the Catalyst Museum, the only science museum in the UK solely devoted to chemistry.
Spike Island was the site of a famous outdoor concert by The Stone Roses in May 1990. A film about the concert was released in 2013, and is called Spike Island.
