The Austrian armed forces started removing the last piece of heavy artillery from the Austrian-Slovenian border. A cannon with a range of 28 kilometres was deployed at a hidden location on Haberberg mountain, near the Slovenian border, some time during the 1970s. The artillery on the mountain was said to have covered the entire Slovenian border with the Austrian Carinthia, thus setting up a military "Iron Curtain". As the information of the Austrian armed forces indicates, the nine-tonne cannon from the Cold War was removed because it has become old and obsolete. Moreover, the political situation in Europe has changed and the cannon will find its place in a military museum in Vienna.
