The Allied Museum () is a museum in Berlin. It documents the political history and the military commitments and roles of the Western Allies (US, France and Britain) in Germany – particularly Berlin – between 1945 and 1994 and their contribution to liberty in Berlin during the Cold War era. Location: American Sector The museum is located on Clayallee, an arterial road named after General Lucius D. Clay (1898–1978), in the Dahlem quarter of the southwestern Steglitz-Zehlendorf borough. Until German reunification in 1990, the area was located in the American sector of postwar West Berlin. The buildings near the US Army headquarters then housed an American movie theater, called Outpost, and the Nicholson Memorial Library. The museum was inaugurated in 1998, on the fiftieth anniversary of the Berlin airlift, in the presence of Chancellor Helmut Kohl. Entrance is free. Since the closure of Berlin Tempelhof Airport in 2008, the Allied Museum has announced its interest in relocating to the old airport at some point. The Allies The museum shows an important part of the military and political scenery of the Cold War in Berlin, from immediately after World War II and the final disengagement of the Allied forces in the 1990s. The early period of partition plans evolved by the European Advisory Commission is documented. When in February 1945, the United States, Great Britain, and the Soviet Union decided to split the former German Reich in occupation zones at the Yalta Conference, including a fourth area assigned to the French, the German capital likewise was divided into four sectors. In late April, Soviet Red Army troops fought their way into the city during the Battle of Berlin and enforced the unconditional surrender by the German Wehrmacht armed forces. In Summer they pulled out from the city's Western sectors according to the agreements concluded. In the beginning East-West conflict, first marked by the withdrawal of the Soviet representatives from the Allied Kommandatura and the following Berlin Blockade in 1948–49, the US, Britain and France formed the Western Allies and came in opposition to the Soviet occupation forces. The increasing tensions culminated in the Berlin Crisis of 1961 and the building of the Berlin Wall. A significant step towards the easing of tensions was made in the 1971 Four Power Agreement on Berlin, until the "Berlin question" was solved after the East German Peaceful Revolution and the fall of the Berlin Wall
