Deeside (Glannau Dyfrdwy) is the name given to a predominantly industrial conurbation of towns and villages in Flintshire and Cheshire on the Wales–England border lying near the canalised stretch of the River Dee that flows from neighbouring Chester into the Dee Estuary. These include Connah's Quay, Shotton, Queensferry, Aston, Garden City, Sealand, Broughton, Bretton, Hawarden, Ewloe, Mancot, Pentre, Saltney and Sandycroft. The population is around 50,000, with a plurality (17,500) living in Connah's Quay. Deeside is known for its industry, providing jobs for the people of Cheshire, Merseyside and North Wales. The biggest employment area in Deeside is Deeside Industrial Park, located on the north bank of the Dee on the southern edge of the Wirral peninsula, which has both historical and contemporary significance, and provides Deeside and the surrounding area with jobs in many different industries from construction to food production. Deeside is also home to steel manufacturer Tata Steel and Toyota's highly advanced engine manufacturing plant. Shotton's history dates back around 1000 years to Saxon times. Various settlements within the Deeside area are recorded in the Domesday book (1086) which list them within the Cheshire Hundred of Ati's Cross. They are Aston, Broughton, Clayton, Hawarden, Golftyn and Wepre. The largest of these was Hawarden with 14 households. As a border region, the Deeside area was subject to frequent conflict between the Welsh and the English in the twelfth and thirteenth centuries. In the Battle of Ewloe in 1157, Owain Gwynedd inflicted a notable defeat on the forces of Henry II. Ewloe Castle was built by Llywelyn the Great in the early thirteenth century to secure the area. Llywelyn's son and successor, Dafydd ap Llywelyn, was born in nearby Coleshill in 1212. Until industrialisation in the nineteenth century, Shotton remained a cluster of hamlets: a settlement comprising Shotton, Nine Houses and Shotton Hall, which itself dates back to 1637.
