exclaves of West Berlin in East Germany, while

itself was an

East German (GDR) territory.
Origin of the exclave
Steinstücken is located on former farmland that once belonged to the village of Wendisch Stahnsdorf, which had probably already been abandoned by the time it was mentioned in the list of villages, towns, and cities commissioned in 1375 by Emperor
Charles IV. The exclave originated in 1787, when farmers of the nearby village of
Stolpe acquired of land outside of their municipality, which included part of the Potsdam Forest. A small settlement was established there in 1817 and was called Steinstücken after a piece of village land where rocks from the ice age had once been found. In 1898 Stolpe joined the new rural community of
Wannsee. When Wannsee became part of the
Zehlendorf borough with the incorporation of
Greater Berlin in 1920, Steinstücken (with the exception of the Potsdam Forest section) was included, although it was not physically connected to the city. Until 1945 this fact was of little significance; daily life was oriented towards
Babelsberg, an adjacent district of
Potsdam.
Cold War
At
the end of World War II in 1945, Berlin's city boundary became the
dividing line between the
Soviet zone of Germany and the American, British and French sectors of Berlin. For the first couple of years, the border still remained open.

.
In 1951, the GDR attempted to annex Steinstücken by sending police and military forces into the exclave. After objection by the United States, they withdrew their forces a few days later. After this event, the residents were no longer allowed access into East Germany; their only access to the outside world was through two East German checkpoints and a road of about 1 km length into the rest of West Berlin. For all their everyday activities (e.g. work, school, shopping, visits of friends and relatives) they had to pass these controls from then on.

regime in East Germany fortified the wall around Steinstücken to cut off this escape route.
Following a helicopter visit by
Lucius D. Clay on 21 September 1961, a US military post was installed in the exclave. Soldiers were regularly flown in by helicopter from then on. Today, a "helicopter memorial" commemorates these circumstances.
The corridor

To alleviate the enormous inconvenience of daily border crossings, a road connecting Steinstücken to
Kohlhasenbrück, the most adjacent neighborhood of Wannsee, was built in 1972. This required an exchange of territory between East Germany and West Berlin, which in turn required the approval of the four occupation powers: the

. Following meetings of the
Allied Commission, the four powers signed the
Four Power Agreement on Berlin"Ostpolitik: The Quadripartite Agreement of 3 September 1971"
(U.S. Diplomatic Mission to Germany) on 3 September 1971. This resolved a number of irregularities in the border between East Germany and West Berlin, and made a tiny sliver of land connecting the rest of West Berlin to Steinstücken a part of West Berlin territory. In return, West Berlin ceded six uninhabited exclaves to East Germany and paid four million West German Deutsche Mark
The Deutsche Mark (; "German mark (currency), mark"), abbreviated "DM" or "D-Mark" (), was the official currency of West Germany from 1948 until 1990 and later of unified Germany from 1990 until the adoption of the euro in 2002. In English, it ...
s. A connecting road, Bernhard-Beyer-Straße, was then built on this sliver, allowing Steinstücken residents to cross unimpeded to the rest of West Berlin. As the new border enclosed the road, extensions of the Berlin Wall were built on either side. The land transfer and building of the road ended Steinstücken's status as an exclave for all practical purposes.
Another complication was the fact that railway tracks bisected Steinstücken, and residents used the Stahnsdorfer Straße bridge at the northern edge of the neighborhood to cross from one side to the other. East Germany refused to transfer the territory occupied by the bridge to West Berlin, because the railway tracks below belonged to the East German-owned Deutsche Reichsbahn
The ''Deutsche Reichsbahn'' (), also known as the German National Railway, the German State Railway, German Reich Railway, and the German Imperial Railway, was the Weimar Republic, German national Rail transport, railway system created after th ...
. A compromise was reached in which the bridge and the airspace above it became part of West Berlin, while the airspace and land below the bridge, including the tracks, remained in East German hands.
Following the reunification of Germany, the heavily-fortified international border around Steinstücken was dismantled and the neighborhood has become seamlessly integrated with surrounding Babelsberg. However, the former border remains as the boundary between the states of Berlin and Brandenburg
