Map - Aberdeen

Aberdeen (Aiberdeen ; Obar Dheathain ; Aberdonia) is a city in North East Scotland, and is the third most populous city in the country. Aberdeen is one of Scotland's 32 local government council areas (as Aberdeen City ), and has a population estimate of for the city of Aberdeen, and for the local council area making it the United Kingdom's 39th most populous built-up area. The city is 93 mi northeast of Edinburgh and 398 mi north of London, and is the northernmost major city in the United Kingdom. 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.

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. There are two universities in Aberdeen: the University of Aberdeen, founded in 1495 and located in Old Aberdeen, and Robert Gordon University which is located in Garthdee area and received university status in 1992.

In 2012, HSBC named Aberdeen as a leading business hub and one of eight 'super cities' spearheading the UK's economy, marking it as the only city in Scotland so designated. In 2018, Aberdeen was found to be the best city in the UK to start a business in a study released by card payment firm Paymentsense.

The Aberdeen area has seen human settlement for at least 8,000 years. The city began as two separate burghs: Old Aberdeen at the mouth of the river Don; and New Aberdeen, a fishing and trading settlement, where the Denburn waterway entered the river Dee estuary. The earliest charter was granted by William the Lion in 1179 and confirmed the corporate rights granted by David I.

In 1319, the Great Charter of Robert the Bruce transformed Aberdeen into a property-owning and financially independent community. Granted with it was the nearby Forest of Stocket, whose income formed the basis for the city's Common Good Fund which still benefits Aberdonians.

During the Wars of Scottish Independence, Aberdeen was under English rule, so Robert the Bruce laid siege to Aberdeen Castle before destroying it in 1308, followed by executing the English garrison. The city was burned by Edward III of England in 1336, but was rebuilt and extended. The city was strongly fortified to prevent attacks by neighbouring lords, but the gates were removed by 1770.

Aberdeen's medieval council registers survive from 1398 onwards and are exceptional for their quantity and continuity among surviving Scottish burgh records. The earliest eight volumes, from 1398 to 1511, have been included in the UNESCO UK Memory of the World Register, and have been edited in a digital edition.

During the Wars of the Three Kingdoms of 1644 to 1647 the city was plundered by both sides. In 1644, it was taken and ransacked by Royalist troops after the Battle of Aberdeen and two years later it was stormed by a Royalist force under the command of the George Gordon, 2nd Marquis of Huntly. In 1647 an outbreak of bubonic plague killed a quarter of the population. In the 18th century, a new Town Hall was built and the first social services appeared with the Aberdeen Infirmary at Woolmanhill in 1739 and the Aberdeen Lunatic Asylum in 1800.

The expensive infrastructure works led to the city becoming bankrupt in 1817 during the Post-Napoleonic depression, an economic downturn immediately after the Napoleonic Wars; but the city's prosperity later recovered. The increasing economic importance of Aberdeen and the development of the shipbuilding and fishing industries led to the construction of the present harbour including Victoria Dock and the South Breakwater, and the extension of the North Pier. Gas street lighting arrived in 1824 and an enhanced water supply appeared in 1830 when water was pumped from the Dee to a reservoir in Union Place. An underground sewer system replaced open sewers in 1865. The city was incorporated in 1891. Although Old Aberdeen has a separate history and still holds its ancient charter, it was annexed by the City of Aberdeen in 1891.
