Serbia

Serbia is a country on the Balkan Peninsula in southeastern Europe with plateaus in the north and mountains and ski resorts in the south. In the capital, Belgrade, there are buildings from the communist era and Kalemegdan Park. Here is the Belgrade Fortress, which successively belonged to the Roman, Byzantine, and Ottoman Empires. Stari Grad, Belgrade's old town, is home to 19th-century villas and the Belgrade National Theater, where opera and ballet performances can be seen. ― Google
