The English county of South Yorkshire includes the town of Doncaster. It is the administrative hub of the larger Metropolitan Borough of Doncaster and is named after the River Don. It is South Yorkshire's second-largest town after Sheffield, with whom it shares the international Doncaster Sheffield Airport, located 10 kilometres to the southeast. Doncaster, a significant regional town with crucial transportation connections and fun attractions, was established by the Romans. Additionally, it has a market. The second-biggest city in South Yorkshire, Doncaster is also the largest metropolitan region in England. With the growth of coal mining, its population increased significantly. The town's service industry expanded as a result of the good communication links with the rest of the UK following the economic challenges brought on by the closure of coal mines in the 1970s and early 1980s.
