 To that point, the university was housed in several older structures around the neighborhood, including the Otto Hahn building, which houses the "Department of Biochemistry" to this day.Thanks to further donations from the United States, Free University of Berlin was able to construct several new central building complexes including the Benjamin Franklin university clinic complex.The largest single complex of university buildings is the "Rost- und Silberlaube", which translates roughly to the "Rust and Silver Lodges".
