The University of Glasgow is the fourth-oldest university in the English-speaking world and one of Scotland's four ancient universities. Located in Glasgow, the university was founded in 1451 and is presently one of seventeen British higher education institutions ranked amongst the top 100 of the world. A major centre of the Scottish Enlightenment during the 18th century, from the 19th century it became a pioneer in British higher education by providing for the educational needs of students from the growing urban and commercial classes, as opposed to the upper class. Glasgow served these students by preparing them for professions outwith commerce - the law, medicine, teaching, and the church. It also trained smaller numbers for careers in science and engineering. More recently it was the Sunday Times "Scottish University of the Year" for 2007 and the university is currently a member of the Russell Group and of Universitas 21. Since 1870, the main University campus has been located on Gilmorehill in the West End of the city. Additionally, there are a number of university buildings elsewhere in the city, a facility at Loch Lomond, the University Marine Biological Station Millport and the Crichton Campus in Dumfries (which is jointly operated alongside a number of other institutions). Glasgow has departments of Law, Medicine, Veterinary Medicine, and Dentistry—a position that is unique amongst the other universities in Scotland.
