I got this one from Renato as a part of Choose a Country RR special group #600. It shows King's Church, a part of Studenica monastery in central Serbia.
The Studenica monastery is a 12th-century Orthodox monastery. It is one of the largest and richest Serb Orthodox monasteries. Stefan Nemanja, the founder of the medieval Serb state, founded the monastery in 1190. The monastery's fortified walls encompass two churches: the Church of the Virgin, and the Church of the King, both of which were built using white marble. In 1986 UNESCO included Studenica monastery on the list of World Heritage Sites.
Serbian postal service issued a stamp in 2008 representing Đavolja Varoš, a peculiar rock formation. It features 202 exotic formations described as earth pyramids or "towers", as the locals refer to them. They are 2-15 m tall and 4-6 m wide at the base.
