The Telefunken Hochhaus at Ernst-Reuter-Platz in Berlin Charlottenburg. The highrise building has 22 floors and with its 80 meters it once was the highest building of Berlin, until the Europa-Center was built in 1965. The building was built as the headquarters of the company Telefunken. When Telefunken and AEG become one company in 1975, the building was acquired by the city of Berlin.
For the past decades most of the building was used by the Technical University TU Berlin.
