Opened in 1984 and located in an old semi-detached villa in Frankfurt am Main, the German Architecture Museum is dedicated exclusively to the topic of architecture. At the heart of the building, the "Haus-im-Haus" (house within a house) takes visitors on a fascinating journey over three floors before finally ending at a "prehistoric hut". The permanent exhibition with models ranging from the primitive hut to the skyscraper offers an insight into mankind's history of buildings and settlements. The museum also hosts a number of special exhibitions throughout the year. Closed on Mondays.
