The administrative county of Flintshire was abolished under the Local Government Act 1972 on April 1, 1974, becoming part of the new county of Clwyd. The exclaves became part of Wrexham Maelor district - other parts formed the districts of Alyn and Deeside, Delyn and Rhuddlan. A principal area named Flintshire was formed in 1996 under the Local Government (Wales) Act 1994, consisting only of the Alyn and Deeside and Delyn districts - the Wrexham Maelor parts now form part of Wrexham county borough, with the former Rhuddlan district forming part of the Denbighshire principal area.
Flintshire is a maritime county bounded to the north by the Irish Sea, to the northeast by the Dee estuary, to the east by Cheshire and to the south and southwest by Denbighshire. The Maelor Saesneg, was bounded on the northwest by Denbighshire, on the northeast by Cheshire, and on the south by Shropshire.
Flintshire is the smallest historic county in Wales. The coast along the Dee estuary is heavily developed by industry and the north coast much developed for tourism. The Clwydian Mountains occupy much of the west of the county. The highest point is Moel Fammau (1,820 feet / 554 metres). The chief towns are Buckley, Connah's Quay, Flint, Hawarden, Holywell, Mold, Queensferry, and Shotton. The main rivers are the Dee (the estuary of which forms much of the coast) and the Clwyd. The main industries are manufacturing of aircraft components (Airbus), engines (Toyota), paper (Shotton Paper), steel processing (Corus), agriculture and tourism.
Places of special interest include castles in Flint, Hawarden, Rhuddlan and Ewloe, and Wepre Country Park, Connah's Quay.
