Djavolja Varos (”Teufel Stadt”) (Süd-Ost Serbien)
In the south-eastern of Serbia, 27 km south-east of Kursumlija, lies a first-class natural landmark –
Djavolja Varos (”Devil’s Town”). Two rare natural phenomena at the same spot: 202 stone formations created by erosion, between two and 15 meters in height and the middle diameter of under 1 m, topped by stone blocks weighing as much as 100 kg, appearing unreal and yet lasting for centuries, and two springs of extremely acid water (pH 1,5) with high mineral content (15 g/l; content of some elements even 1000 times as high as in ordinary drinking waters) make Djavolja Varos a true wonder of nature.
In 2007, the site was a nominee in the New Seven Wonders of the World election.
