Cleveland /ˈkliːvlənd/ is a land of hills and dales from the River Tees to Vale of Pickering, England.
[1] Cleveland has a centuries-long association with the area from Middlesbrough to Pickering and Thirsk to Whitby, effectively the eastern half of Yorkshire's North Riding.
The Cleveland Hills were key suppliers of the ironstone which was essential to running blast furnaces alongside the River Tees.
Teesport is one of the United Kingdom's main ports, initially due to the iron boom, with other heavy industrial plants between Middlesbrough and Redcar.
The county of Cleveland followed on similar boundaries, also including areas north of the River Tees.
