Did you know that 18 Roman emperors were born on the territory of modern-day Serbia—more than anywhere else outside of Italy? Serbia, often overlooked for its ancient past, is actually home to some of the most significant Roman archaeological sites in Europe. The Roman Emperors Route invites history lovers and cultural travelers to uncover ruins, imperial palaces, and roads once walked by emperors themselves.

Here’s your 5-day travel itinerary through Serbia’s rich Roman legacy.

Day 1: Belgrade – Singidunum and the Gateway to the Empire
