Created at the Polish Pavilion by the Institute of Architecture and Jakub Woynarowski, the exhibition Impossible Objects deals with the relations between modernism and politics in the context of building a modern nation state. The show’s highlight is a natural-scale replica of the canopy over the entrance to the burial crypt of Marshal Józef Piłsudski, the Polish political and military leader, created in 1937 at the Wawel Cathedral in Kraków according to a design of Adolf Szyszko-Bohusz. Several alternative variations of the canopy presented by the architect illustrate the process of arriving at a modernist form: from historicising loftiness to modern simplification.
