One of the most significant (and definitively most famous) is monumental mausoleum to Unknown Hero provided by sculptor Ivan Meštrović on initiative of King Alexandar I Karađorđević to commemorate enormous victims who gave their lives for unification and defense of the country that was about to be born. Even though Serbs consisted more than 90% of overall victims in WWI on the territories of future Kingdom, in order to support Yugoslav unity king has ordered that this monument consists statues/pillars commemorating all the nations over whom he has governed: Sumadinka, Panonka, Crnogorka, Kosovarka - Serbs; Dalmatinka, Zagorka - Croats; one Slovenian and one Macedonian ("old Serbian"). Mausoleum is placed on position of Middle Age town of Žrnov which ruins now can be seen only at photos.

On the mountain was also placed one of the Belgrade symbols - Avala TV Tower which was a 202.87 meters (666 feet) tall telecommunication tower that was open for visitors and visible throughout Belgrade. Its building started in 1963 and was finished in 1965. It was destroyed on April 29, 1999, by NATO bombardment during the Kosovo War, supposedly to put Radio Television of Serbia off the air. It was the only tower in the world to have an equilateral triangle as its cross section as it was one of very few towers not perched directly into ground, but standing on their legs. It was, also, the only tower in the world mounted on a tripod. From its construction in 1965 to its destruction on April 29, 1999 it was the tallest building in the Balkans and until September 11, 2001. it was the tallest building ever destroyed. Its reconstruction has begun as of 2006 and is scheduled for opening within a year

At the foothill, on the road to Belgrade suburbia called Kumodraž is located a home of duke Stepa Stepanović, famous Serbian army commander who become glorious for winning first battle in the name of allied troops in World War I.
