Belgrade is the capital city of Serbia. Besides the Danube and Sava rivers, one of its most prominent landmarks is Beogradska Tvrđava - an impressive fortress situated where the two rivers meet. The city was of strategic importance to major civilizations like the Romans and Byzantine empires in the past, and remnants of this are still evident in structures like the Church of Saint Sava and Kalemegdan Park.
