 Traditionally, agriculture was the mainstay of the economy of this part of Wales, but with the Industrial Revolution, the North Wales Coalfield was developed and parts of eastern Clwyd around the Dee estuary and Wrexham became industrialised. The advent of the railway running from Chester along the North Wales coast in the mid-nineteenth century made it easy for urban dwellers from Lancashire and Cheshire to visit the seaside towns of North Wales, and nowadays, tourism is the main source of income in Clwyd.
