Tartu is a city in eastern Estonia. It’s known for the prestigious, 17th-century University of Tartu. The old town centers on the university’s neoclassical main building, and the cafe-filled Town Hall Square, home to the Kissing Students fountain. The modern Science Centre AHHAA has hands-on exhibits and a 4D cinema. The ruined Tartu Cathedral, in hilltop Toomemägi Park, has 2 restored towers with viewing platforms.
