Belgrade

Belgrade is the capital of Serbia, renowned for its vibrant nightlife, diverse culture, and incredible thermal baths. It is also known for the beautiful Belgrade Fortress. Situated at the confluence of two major rivers -- the Sava and the Danube -- the fortress is a testament to Serbia's history and heritage, and has been standing since the 3rd century BC. From the terrace of the fortress, you can get stunning views of the city, and a river cruise along the Sava is also a must. Within the walls, admire the Roman city walls and gates from the 19th century and walk along the lush park surrounding the fortress, lined with incredible monuments and structures. Be sure to visit the Kalemegdan Museum, located within the fortress, to learn about Belgrade's rich cultural heritage, learn about the Serbian Orthodox Church, and get a taste of the region's Ottoman past.
