Adesivo Flag of the county of Flintshire, Wales

Flintshire (Welsh: Sir y Fflint) is a county in the north-east of Wales. It borders the Irish Sea to the north, the Dee Estuary to the north-east, the English county of Cheshire to the east, Wrexham County Borough to the south, and Denbighshire to the west. Connah's Quay is the largest town, and Flintshire County Council is based in Ewloe. The county covers 169 square miles (440 km2), with a population of 155,000 in 2021. After Connah's Quay (16,771), the largest settlements are Flint (13,736), Buckley (16,127) and Mold (10,123). The east of the county is industrialised and contains the Deeside conurbation, which extends into Cheshire and has a population of 53,568. The adjacent coast is also home to industry, but further west has been developed for tourism, particularly at Talacre. Inland, the west of the county is sparsely populated and characterised by gentle hills, including part of the Clwydian Range and Dee Valley AONB. The county is part of the preserved county of Clwyd. The county is named after the historic county of the same name, which was established by the Statute of Rhuddlan in 1284 and has notably different borders. The county is considered part of the Welsh Marches and formed part of the historic Earldom of Chester and Flint.
