The Detlev-Rohwedder-Haus (Detlev Rohwedder House) is a building in Berlin that at the time of its construction was the largest office building in Europe. It was constructed between February 1935 and August 1936 to house the German Ministry of Aviation (Reichsluftfahrtministerium, or RLM), headed by Herman Goering, a prominent Nazi.
During the German Democratic Republic (East Germany) it was known as the Haus der Ministerien ("House of Ministries"). In 1992 it was named the Detlev Rohwedder Building, in honour of Detlev Karsten Rohwedder, the assassinated head of the Treuhand, which had its headquarters there 1991-95. Still, the building is more commonly known as the Air Ministry Building. Since 1999, the building is the seat of the German Finance Ministry.
