King's College in Old Aberdeen, Scotland, the full title of which is The University and King's College of Aberdeen (Collegium Regium Abredonense), is a formerly independent university founded in 1495 and now an integral part of the University of Aberdeen. Its historic buildings are the centrepiece of the University of Aberdeen's Old Aberdeen campus, often known as the King's or King's College campus.
The focal point of the college, as well as its oldest building, is the late 15th century King's College Chapel. A number of other historic buildings remain, with others being subject to renovation and rebuilding in the 18th and 19th centuries. In the early 20th century, a great deal of expansion saw the university buildings increase around the historic college buildings. In the later 20th century, the university expanded dramatically in size, dominating Old Aberdeen and expanding out from the High Street with a number of modern buildings.
King's College was the first university in Aberdeen, the third in Scotland and the fifth in the British Isles. In 1495, William Elphinstone, the relatively newly appointed Bishop of Aberdeen, petitioned Pope Alexander VI on behalf of King James IV to create the facility to cure the ignorance he had witnessed within his parish and in the north generally. A papal bull was issued in February 1495 (1494 in the calendar of the day) founding the university; a royal charter later that year recognised Aberdeen's status as equal to that of Scotland's two existing universities at Glasgow and St Andrews. As a former professor at the University of Paris, Elphinstone modelled the university very much on the continental European tradition. Hector Boece, a fellow professor at Paris, was awarded the status of first principal of the new institution.
It would not be until 1509, with the issuance of a charter by Elphinstone, that university life at King's truly began. Construction of the chapel began in 1498; it was consecrated in 1509 and dedicated to St Mary. By 1514, the university had some forty-two members in the form of both staff and students.
