Blyth, Northumberland

Blyth is a town in the district of Blyth Valley, Northumberland, England, lying to the south of the River Blyth.

In the medieval period, Blyth grew as its salt pans were exploited. It then became a centre for coal mining, while its harbour was developed to export the local coal. Shipbuilding was also important in the town, and it was a submarine base during both World Wars.
