Bennerley Viaduct is a grade 2* listed railway viaduct built in 1877 by the Great Northern Railway Company. At over quarter of a mile long, it is the longest wrought iron viaduct in the country. It straddles the River Erewash connecting Ilkeston in Derbyshire with Awsworth in Nottinghamshire. The “Iron Giant” has been described by the World Monuments Fund as being an “extraordinary monument” meriting inclusion in the 2020 World Monuments Watch, one of only 25 sites chosen globally. Historic England consider the viaduct is a “stunning example of the genius of British Engineering”.
