Aberdeen, United Kingdom

Being situated between two river mouths, the city has little natural exposure of bedrock. The small amount of geophysics done, and occasional building-related exposures, combined with small exposures in the banks of the River Don, suggest that it is actually sited on an inlier of Devonian "Old Red" sandstones and silts. The outskirts of the city spread beyond the (inferred) limits of the outlier onto the surrounding metamorphic/ igneous complexes formed during the Dalradian period (approximately 480–600 million years ago) with sporadic areas of igneous Diorite granites to be found, such as that at the Rubislaw quarry which was used to build much of the Victorian parts of the city.

The city extends to 186 km2 (72 sq mi), and includes the former burghs of Old Aberdeen, New Aberdeen, Woodside and the Torry area to the south of River Dee. In 2025, this gave the city a population density of 1,240 inhabitants per square kilometre (3,200/sq mi). The city is built on many hills, with the original beginnings of the city growing from Castle Hill, St. Catherine's Hill and Windmill Hill. When compared to mainland Europe, Aberdeen is further north than almost all of Denmark and plenty of southern Sweden, being just south of Gothenburg in terms of latitude.

Traditionally, Aberdeen was home to fishing, textile mills, shipbuilding and paper-making. These industries have been largely replaced. High technology developments in the electronics design and development industry, research in agriculture and fishing and the oil industry, which have been largely responsible for Aberdeen's economic growth, are now major parts of Aberdeen's economy.

Until the 1970s, most of Aberdeen's leading industries dated from the 18th century; mainly these were textiles, foundry work, shipbuilding and paper-making, the oldest industry in the city, with paper having been first made there in 1694. Paper-making has reduced in importance since the closures of Donside Paper Mill in 2001 and the Davidson Mill in 2005 leaving the Stoneywood Paper Mill with a workforce of approximately 500. Textile production ended in 2004 when Richards of Aberdeen closed.

Grey granite was quarried at Rubislaw quarry for more than 300 years, and used for paving setts, kerb and building stones, and monumental and other ornamental pieces. Aberdeen granite was used to build the terraces of the Houses of Parliament and Waterloo Bridge in London. Quarrying finally ceased in 1971. The current owners have begun pumping 40 years of rainwater from the quarry to develop a heritage centre on the site.

The city has a wide range of cultural activities, amenities, and museums, and is regularly visited by Scotland's National Arts Companies. It was awarded the Nicholson Trophy for the best-kept town at the Britain in Bloom contest in 1975.

The Aberdeen Art Gallery houses a collection of Impressionist, Victorian, Scottish and 20th-century British paintings as well as collections of silver and glass. It also includes The Alexander Macdonald Bequest, a collection of late 19th-century works donated by the museum's first benefactor and a constantly changing collection of contemporary work and regular visiting exhibitions. The Aberdeen Art Gallery reopened in 2019 after a four-year refurbishment costing £34.6m.

The Aberdeen Maritime Museum, located in Shiprow, tells the story of Aberdeen's links with the sea from the days of sail and clipper ships to the latest oil and gas exploration technology. It includes an 8.5-metre-high (28 ft) model of the Murchison oil production platform and a 19th-century assembly taken from Rattray Head lighthouse

Aberdeen has two universities, the ancient University of Aberdeen, and Robert Gordon University, a modern university often referred to as RGU. Aberdeen has a high proportion of students of 11.5%, higher than the national average of 7%.

The University of Aberdeen began as King's College, Aberdeen, which was founded in 1495 by William Elphinstone (1431–1514), Bishop of Aberdeen and Chancellor of Scotland. Marischal College, a separate institution, was founded in New Aberdeen by George Keith, fifth Earl Marischal of Scotland in 1593. These institutions were merged by the Universities (Scotland) Act 1858 to form the University of Aberdeen. The university is the fifth oldest in the English-speaking world and offers degrees in a full range of disciplines. Its main campus is in Old Aberdeen in the north of the city and it currently has approximately 14,000 students. The university's debating society is the oldest in Scotland, founded in 1848 as the King's College Debating Society. Today, Aberdeen is consistently ranked among the top 200 universities in the world and is ranked within the top 20 universities in the United Kingdom. Aberdeen was also named the 2019 Scottish University of the Year by The Times and Sunday Times Good University Guide. In early 2022, Aberdeen opened the Science Teaching Hub.
