Mitchell Library, Glasgow

Europe's largest reference library takes its name from the tobacco tycoon, Stephen Mitchell. Founded in 1874 and open to the public since 1911, it now houses over 1,000,000 books and documents. Wander around the spacious rooms and admire the celebrated dome. There is a huge selection of aerial photography covering most of Glasgow and it's an excellent place to visit if you are interested in the city's history. The famous Mitchell Theatre is part of the same complex.
