On the crossroads of the region's main rivers, Danube and Sava, Belgrade was always an important center of power- but far from just politics! Roam the downtown for the main state buildings, and then visit Saint Sava Temple, one of the biggest Orthodox temples in the world. Next, you can visit the Museum of Nikola Tesla, the father of alternating-current electricity and wireless communications, and Crvena Zvezda football stadium. Wrap it all up with the tale of Tito, leader of the former Yugoslavia and the Non-Aligned Movement.
