Located beautifully along Frankfurt’s Main riverbank, the Deutsches Architekturmuseum (DAM) is Germany’s most significant architecture museum. The striking building itself is an architectural masterpiece over four floors with a magnificent courtyard. Famous architect Oswald Mathias Ungers, who significantly influenced contemporary German architecture with his rational design based on cubic forms, created a “house-in-a-house” behind the facade of the neo-classicist villa. The museum’s library comprises more than 30,000 publications on architectural history dating back to 1800 and the museum’s permanent collection includes over 200,000 files of architectural significance including works by Gottfried Semper.
