The German Democratic Republic, which consisted geographically of what is now eastern Germany, had an area of 107,771 km2 (41,610 mi2), bordering Czechoslovakia in the south, West Germany in the south and west, the Baltic Sea to the north, and Poland in the east.
Much of the territory of the former East Germany lay on the North German Plain and was largely flat and agricultural apart from low morainic hills left by the ice age. However in the south the land rose to the Ore Mountains and Elbe Sandstone Mountains that formed the border with its Communist neighbour, Czechoslovakia.
