About Leeds

Learn more about the host city, Leeds.

Leeds is the largest city in the county of West Yorkshire and the third largest city in Britain, though its urban area size falls behind that of Manchester. Once a major industrial centre, the city today is better known for being the largest UK financial centre outside London, and for its impressive shopping, nightlife, universities and sports facilities. Leeds also has a growing cultural reputation, being home to many museums, restaurants and theatres, and a mixture of Georgian, Victorian, 20th and 21st century architecture.
