Tartu (historical name: Dorpat) is the second largest city of Estonia, with a population of 101,297 (as of 2004) and an area of 38.8 km². In contrast to Estonia's political and financial capital Tallinn, Tartu is often considered the intellectual and cultural centre, especially since it is home to Estonia's oldest and most renowned university. Situated 186 km southeast of Tallinn, Tartu is the centre of Southern Estonia. The Emajõgi River, which connects the two largest lakes of Estonia, crosses the city for a length of 10 km. The city is served by Tartu Airport, and during the Cold War was home to Tartu air base.
