The South-east wall was a system of fortifications planned by Nazi Germany in the late stages of World War II to extend along the Little Carpathians and Lake Neusiedl southwards to the Drava (Drau) river. Not a wall in the true sense of the word, the South-east wall was rather a series of German batteries and anti-tank ditches built at strategic locations alongside the southeastern border of the German Reich in 1944/45 with the intention of stopping the Red Army.
