Aberdeen (/ˌæbərˈdiːn/ AB-ər-DEEN; locally [ˌeːbərˈdin] or [ˈeːbərdin] ; Scottish Gaelic: Obar Dheathain [ˈopəɾ ˈʝɛ.ɪɲ]) is a city in North East Scotland, and is the third most populous Scottish city. Historically, Aberdeen was within the historic county of Aberdeenshire, but is now separate from the council area of Aberdeenshire.
Aberdeen is one of Scotland's 32 local government council areas (as Aberdeen City), and has a population of 198,590 (mid-2020 est.) for the urban area, making it the United Kingdom's 39th most populous built-up area, and 224,190 (2022) for the wider council area including outlying localities. The city is 127 mi (204 km) northeast of Edinburgh and 536 mi (863 km) north of London. Aberdeen has a long, sandy coastline and features an oceanic climate, with cool summers and mild, rainy winters.
During the mid-18th to mid-20th centuries, Aberdeen's buildings incorporated locally quarried grey granite, which may sparkle like silver because of its high mica content. Since the discovery of North Sea oil in 1969, Aberdeen has been known as the offshore oil capital of Europe. Based upon the discovery of prehistoric villages around the mouths of the rivers Dee and Don, the area around Aberdeen has been thought to have been settled for at least 6,000 years.
