Less than a half hour train ride from Brussels, Leuven is home to Belgium's oldest university. As a result, roughly half of the city's 90,000 inhabitants are students, who give the city a lively, informal air - and help sustain the many bars and cafes! Highlights include the Grote Markt (home to the Stadhuis and St Pieterskerk), as well as the Oude Markt and the Groot Begijnhof.
