Occupying a sprawling plot of land just southwest of the train station, the Poznań Congress Center is home to the Poznań International Trade Fairs, which date back to 1921 and currently constitute 55% of the Polish exhibition industry. The total number of visitors attending the sixty or so trade fair events each year - everything from welding to horticulture and from logistics to beach fashion - usually reaches half a million. The complex includes 150 thousand square metres of exhibition space (that's 16 air-conditioned halls) and 77 modern conference rooms.
