South Yorkshire is a metropolitan county in northern England, comprising the city of Sheffield and the metropolitan boroughs of Rotherham, Barnsley and Doncaster. Once the heartland of Britain's steel and coal industries, the county has undergone significant regeneration since the 1980s and now boasts thriving universities, retail centres and cultural venues. Sheffield, the county's largest city, is famous for its steel heritage, green spaces — it has more trees per person than almost any other city in Europe — and a vibrant music and arts scene.
