of all, the most famous was the massive gosprom building (1925–1928), which would become a symbol of not only kharkiv, but constructivism in general. built by architects sergei serafimov, s. kravets and m. felger, and only in three years it would become the highest structure in europe, and its unique feature lies in the symmetry which can only be felt at one point, in the centre of the square. as a tribute to the engineering design by kharkiv's technical university, none of the attempts to blow the building during the second world war were successful, and it still remains the symbol of kharkiv today.
