 Mission Berlin was located on Clayallee in an upscale suburban part of West Berlin called Zehlendorf.Berlin was an occupied city (a title held until 1994, when foreign forces officially left Berlin), with a status very different than any other part of East or West Germany.Under these conditions U.S. Mission Berlin was in many matters under the authority of the commanding U.S. General in West Berlin, and not under the authority of the U.S. Embassy in Bonn, thus operating in a historically unique position.
