"And this building here is Derzhprom, which for lots of people makes the primary impression of Kharkiv. Its full title is – the State Industry Building, but this means different things for different people. The authors of the project Serhiy Serafimov, Samuil Kravets and Mark Felger called their work ""The Uninvited Guest"". ""Reinforced concrete was shot into the sky,"" this is how Mayakovsky would have described it. And he wouldn't have fallen short of the mark! In 1925, when the construction of Gosprom began, reinforced concrete was still uncommon! The American classic Theodore Dreiser called it ""a miracle seen in Kharkiv."" Another peculiar fact - real mammoth bones were discovered here, during the construction of the foundation! Now, these mammoths ""live"" in a nearby nature museum. "
