Tourism in Serbia is mostly based in mountains and villages. The most famous mountain resorts are Zlatibor, Kopaonik, and the Tara. There also are a lot of spas in Serbia, one the biggest of which is the Vrnjačka Banja. There is also significant tourism in Belgrade and Novi Sad (the capital of the Vojvodina province), as well to the Exit Festival and the Guča trumpet festival. Serbia is one of Europe's most culturally diverse countries. The borders between large empires ran through the territory of today's Serbia for long periods in history: between the Eastern and Western halves of the Roman Empire; and between the Ottoman Empire and the Austrian Empire (later Austria Hungary). As a result, while the north is culturally Central European, the south is rather more Oriental. Of course, both regions have influenced each other, and so the distinction between north and south is artificial to some extent.
