The Berlin Wall was shorter than the inner German border.
Berlin Wall . Along with the separate and much longer Inner German border ( IGB ) , which demarcated the border between East and West Germany , it came to symbolize a physical marker of the `` Iron Curtain '' that separated Western Europe and the Eastern Bloc during the Cold War . Inner German border . The better-known Berlin Wall was a physically separate , less elaborate , and much shorter border barrier surrounding West Berlin , more than 155 km to the east of the inner German border ( Berlin having been similarly divided by the four powers after World War II , despite the entire city being in the Soviet zone , thus creating an exclave of West Germany surrounded by East Germany ) .
