== History == === Ancient period === The Avala had deposits of ores, most notably lead and mercury's ore of cinnabarite but mining activities which can be traced to the pre-Antiquity times. Archeologist Miloje Vasić believed that the vast mines of cinnabarite (mercury-sulfide) on Avala were crucial for the development of the Vinča culture, on the banks of the Danube circa 5700 BC. Settlers of Vinča apparently melted cinnabarite and used it in metallurgy. The first miners on Avala recorded in history were the Celtic tribe of Scordisci and it is believed that they built the first outpost on the top of the mountain.
