 Following German reunification , the US government announced plans to fully withdraw its troops from Frankfurt , Germany by 1995 , at which time control of the entire site would be restored to the German Federal Government . It was suggested that the building could become the location for the European Central Bank . In 1996 , the state of Hesse bought the building and associated land for the University of Frankfurt . The buildings were refurbished at a cost of 50 Million German Mark ( about US $ 26M or 25M € ) , by the Copenhagen @-@ based architecture practice Dissing + Weitling and were handed over to the university . The complex now houses the Westend Campus of the university , which includes the departments of Philosophy , History , Theology , Classical Philology , Art and Music , Modern Languages and Linguistics , Cultural and Civilization Studies , the Center for North American Studies and the Fritz @-@ Bauer @-@ Institute .
