Modernism

Modern architecture in Poznań began to emerge in the 1930s with buildings like the ZUS office on Dąbrowskiego Street, continuing through the 1980s. The Okrąglak, constructed between 1949 and 1954, is a prominent example, designed by architect Marek Leykam. Built on a circular plan using prefabricated elements, its nine-story cylindrical structure features a flat roof with a central skylight and a surrounding terrace. The facade, without a dominant elevation, is characterized by a glass surface divided by rectangular window openings and vertical "razor blade" partitions.

Other examples of modernist architecture in Poznań include the Alfa Towers on Święty Marcin and the Poznan University of Physical Education building on Królowej Jadwigi Street. Another important modernist monument is the Arena Hall, which was built in 1974 and was inspired by the shape of the Palazzetto dello Sport, a hall constructed in Rome several years earlier.
