The memorial represents the only surviving demonstration of a part of the former Iron Curtain in the then Czechoslovak Socialist Republic. It hermetically closed the state border with Austria and the Federal Republic of Germany. The line of this building has been moved inland several times. The last version was a 20 m wide line with a wire fence and a signal wall, an arable belt treated with a total herbicide and a service asphalt road. The complex of facilities also meant a great impact on the surrounding area and landscape, which is still visible today in the territory of the Podyjí National Park.
