This would be a perfectly ordinary neighbourhood of Berlin or perhaps neighbouring Potsdam visible only on maps that show the border between Berlin and Potsdam if not for its history. While the Berlin border during German partition included a number of enclaves and exclaves, this is the only place where a significant number (some 300 people) ended up on an "island" of West Berlin surrounded by East German territory. Some complicated corridor solutions were applied for people from Steinstücken to be able to get to West Berlin proper without the need for lengthy border formalities. These days, like before partition, people in Steinstücken tend to use the services of Potsdam more than those of Berlin on a day-to-day basis.
Steinstücken, with approximately 300 residents, is a small outlying neighborhood of the Wannsee district in the Berlin borough of Steglitz-Zehlendorf. From the division of Germany in 1949 until a connecting corridor was created in 1971–72, Steinstücken was the only permanently inhabited of twelve original exclaves of West Berlin in East Germany, while West Berlin itself was an enclave controlled by the Western Allies, surrounded by East German (GDR) territory.

Scientists and reactor experts will be there on these days to answer questions about the facility and the safety measures.
This is the number-one bathing and recreation spot in western Berlin, with several beaches, the large Strandbad Wannsee open-air lido and several historic landmarks nearby.
Glienicke Palace, Casino and Garden
This castle is one of Berlin's oldest castles and where Prince Carl used to reside. Be sure to check out Glienicke Bridge, the bridge that became renowned for the exchange of Western and Eastern secret agents. You can also visit Glienicke Park.
Peacock Island Palace
House museum on Max Liebermann, German painter and printmaker. Has about 15 Lieberman paintings.
This museum explains how this house was used for a meeting of senior Nazis to ensure that they all knew that the SS would industrialize the use of mass-murder in disposing of Jews and "undesirables" and to debate a little the logistics of the Holocaust, for which Hitler had already given the orders.
