Built as Karstadt headquarters in 1932 (reinforced concrete skeleton), the „Thousand Windows“ building proved to be too oversized for a department store and was taken over by the „Reichsfinanzministerium“ in 1934. From 1948 on, it was the headquarter of the Berlin police and until the fall of the Berlin Wall in 1989, it was used by the GDR Volkspolizei and as Prison.
1990 Filming for „The Lives of Others“.
