From there it runs eastward ~135 km (84 mi) through Newcastle upon Tyne and Gateshead before emptying into the North Sea at Tynemouth. It is the largest river in Northumberland and the seventh longest in England. Historically vital for coal export and shipbuilding, today it's a focal point for regeneration, culture, and recreation.
