Haus der Technik
The Haus der Technik was an exhibition hall in Königsberg, Germany, now Kaliningrad, Russia.
Constructed from 1924-25 by Hanns Hopp along Waldburgstraße / Wallring between Tragheim and Tragheimsdorf, the brick hall was used to display machinery as part of the Ostmesse trade fair. Its massive hall was larger in size than even the Muscovite Hall in Königsberg Castle. The Nazis renamed it the "Schlageterhaus", after Albert Leo Schlageter, from 1933–45.
The hall's roof was destroyed during World War II. The building and its vicinity were acquired by an investment company in 2004 and have been converted to commercial use in Kaliningrad.
