Sheffield is a city and metropolitan borough in South Yorkshire, England, approximately 160 miles (260 km) northwest of London. It sits in the eastern foothills of the Pennines, at the confluence of the Rivers Don, Sheaf, Rivelin, and Loxley. Known as the "Steel City" for its historical prominence in steel production, Sheffield has evolved into a geographically diverse city with a mix of urban and rural landscapes, with a third of the city lying within the Peak District National Park.
Key attractions in Sheffield include the Sheffield Botanical Gardens, Kelham Island Museum, Millennium Gallery, and the Crucible Theatre, which hosts the World Snooker Championships. The city centre is undergoing a £120 million redevelopment to revitalize retail and public spaces, including new green zones and improved pedestrian access. Sheffield is also experiencing growth in advanced manufacturing and technology, with expansions by high-tech firms and breakthroughs in sustainable materials and automation at the University of Sheffield's innovation campus.
