The Berlin Wall
For almost 30 years, Berlin was a divided city, with a wall cutting through the center of the city. East and West Berlin were separated by the Berlin Wall from 13 August 1961 until 9 November 1989. There are still remnants of the Wall, its memorial sites, and its relics scattered around the city today. These include the East Side Gallery, the Berlin Wall Memorial in Bernauer Strasse, the Berlin-Hohenschönhausen Memorial, a former Stasi detention facility, and the lush Mauerpark. However, the Berlin Wall's remnants can also be seen in less accessible locations like Berlin-Spandau, Berlin-Reinickendorf, or the Cathedral Cemetery.
Even a second row of cobblestones along some Berlin streets designates the path of the Berlin Wall. A fantastic method to ride your bike along the Wall's path is to use the Berlin Wall Cycle Route. The path traverses the city in a manner similar to that of the Berlin Wall. The full cycle path extends over 160 kilometers around West Berlin following the former GDR border.
