The inner German border was the border between the German Democratic Republic and the Federal Republic of Germany from 1949 to 1990. It ran north–south in a 1,381-kilometre-long (858 mi) irregular L-shaped line from Dassow at the Baltic Sea to Eichigt at the border with Czechoslovakia. The better-known Berlin Wall was a physically separate, less elaborate, and much shorter border barrier surrounding West Berlin, more than 170 kilometres (110 mi) to the east of the inner German border.
