Okrąglak (meaning rotunda) in Poznań was constructed between 1948 and 1954 to plans by Polish architect Marek Leykam. The 8-storey modernist building was state of the art for its time: it was the first in Poznań to be constructed out of prefabricated components and also the first to have ceiling heating. Its round shape is a reference to the Sugar Industry Bank building which stood in its place until it was destroyed during World War II.
The Okrąglak served as the Universal Department Store.
A listed building since 2003, the Okraglac was renovated in 2011/2012 and now features over 50000 square meters of office space.
