The Berlin Wall Memorial is the central memorial site of German division, located in the middle of the capital. Situated at the historic site on Bernauer Strasse, it extends along 1.4 kilometers of the former border strip. The memorial contains the last piece of Berlin Wall with the preserved grounds behind it and is thus able to convey an impression of how the border fortifications developed until the end of the 1980s. The events that took place here together with the preserved historical remnants and traces of border obstacles on display help to make the history of Germany's division comprehensible to visitors. The memorial is part of the Berlin Wall Foundation, which also includes the Marienfelde Refugee Center Museum, the central site dedicated to the history of flight and emigration in divided Germany.
