Osijek is particularly famous for its Secessionist architecture, a style very popular throughout the former Austro-Hungarian Empire. The magnificent row of palaces on European Avenue—today mostly used as office spaces and local government buildings—were built at the beginning of the 20th century in the style of the so-called "Viennese secession." However, the largest of these buildings, the Postanska palača, was built in the style of "the Hungarian secession." In the same street there are a number of classicist buildings from the 19th century including the Municipal Court of Osijek. Of all the houses on this street, the most visited would probably be the Museum of Fine Arts, where there is a wealth of paintings and sculptures depicting the region. Some of the most interesting paintings are portraits of Slavonian noble families from the 18th and 19th centuries and the romantic landscapes of Slavonia and Baranja, as well as works of the founder of Osijek's drawing school Hugo Conrad Von Hötzendorff and Adolf Waldinger.
