Mountain Avala is 506 meters high, 18 km from Belgrade. It is under a deciduous and coniferous forest. Avala’s nature complex is under protection from 1859. In the Middle Ages the town of Zrnov was on the mountain top, and controlled the road to Belgrade. Turks take it in 15th century and adapt it to their needs. At the top of the mountain, in 1938,mausoleum-monument of the Unknown Hero was built, a work by Ivan Mestrovic and dedicated to Serbian heroes from World War I. In the vicinity is the monument to Soviet war veterans, killed in the plane crash at that spot on 19. October 1964. On the road to Belgrade, in the village of Jajinci, is a Memorial Park at the site where the Germans, during World War II, executed around 80.000 people. Avala was dominated by a TV tower, 195 meters high, built in 1965. NATO bombs pulled it down. A new TV tower is under construction, should be finished in a year and a half, will be 202 meters high, and look like the old one. On Avala there are restaurants, mountaineers cottages, and a landmark in memory of Vasa Carapic.
