Flintshire is notable as having one of the few large county exclaves (an area known as "English Maelor" or "Maelor Saesneg") to survive the Counties (Detached Parts) Act 1844.

The administrative county of Flint was abolished under the Local Government Act 1972 on 1 April 1974, becoming part of the new administrative area of Clwyd. The exclaves became part of Wrexham Maelor district – other parts formed the districts of Alyn and Deeside, Delyn and Rhuddlan. A unitary authority, also 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 the northernmost part of the current Denbighshire unitary authority.



The historic county does not have the same boundaries as the current administrative Flintshire; in particular it includes a large exclave called Maelor Saesneg; it also includes Prestatyn, Rhyl and St Asaph which are now administered as part of Denbighshire, as well as Bangor-on-Dee and Overton-on-Dee, which are administered as part of Wrexham. Other exclaves of the historic Flintshire include the manors of Marford and Hoseley, Abenbury Fechan and Bryn Estyn, all on the outskirts of Wrexham, and also a small part of the parish of Erbistock around the Boat Inn. These are all completely surrounded by the historic county of Denbighshire. Additionally, a small part of Flintshire, including the village of Sealand, is isolated across the River Dee when its course was changed to improve navigation.

Flintshire is a maritime county bounded to the north by the Irish Sea, to the north-east by the Dee estuary, to the east by Cheshire and to the south and southwest by Denbighshire. The Maelor Saesneg is bounded on the north-west by Denbighshire, on the north-east 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 Famau (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.


The county was formed in 1284 under the terms of the Statute of Rhuddlan, following the defeat of the Principality of Wales. However, the region had been English since the 8th century, and formed part of Cheshire until it was captured by the Welsh in the late 12th century. In the 13th century, prior to its re-capture by the Normans, the region comprised:

Yr Hob and Ystrad Alyn, which been part of Gwynedd earlier in the century, had become sufficiently Welsh that they were regarded as another part of Welsh Maelor, rather than distinguished from it like Maelor Saesneg. They were not initially included in Flintshire, but instead became Marcher Lordships. Yr Hob became the Lordship of Hope, while Ystrad Alyn was split in two - the Lordships of Mold and Hawarden. Following the Laws in Wales Act (1536), these three Lordships were merged into Flintshire.
