Pegatina Flag of the city of Aberdeen, Scotland

Aberdeen (/ˌæbərˈdiːn/ AB-ər-DEEN; locally [ˌeːbərˈdin] or [ˈeːbərdin]; Scottish Gaelic: Obar Dheathain [ˈopəɾ ˈʝɛ.ɪɲ]) is a port 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 City Council is one of Scotland's 32 local authorities (commonly referred to as councils). Aberdeen has a population of 198,590 (2020) for the main urban area and 220,690 (2020) for the wider settlement including outlying localities, making it the United Kingdom's 39th most populous built-up area. Aberdeen has a long, sandy coastline and features an oceanic climate, with cool summers and mild, rainy winters. Aberdeen received royal burgh status from David I of Scotland (1124–1153), which transformed the city economically. The traditional industries of fishing, paper-making, shipbuilding, and textiles have been overtaken by the oil industry and Aberdeen's seaport. Aberdeen Heliport is one of the busiest commercial heliports in the world, and the seaport is the largest in the north-east part of Scotland. A university town, the city is known for the University of Aberdeen, founded in 1495 as the fifth oldest university in the English-speaking world and located in Old Aberdeen. 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 is thought to have been settled for at least 6,000 years.
