Belgrade Fortress

Overview

Belgrade Fortress stands at the strategic confluence of the Danube and Sava rivers, crowning the ridge of Kalemegdan. Built and rebuilt over two millennia by Romans, Byzantines, Ottomans, and Austrians, it remains the city's most powerful symbol of resilience — destroyed and reconstructed more than 40 times.

Highlights

• Zindan Gate: The imposing 15th-century Ottoman gate, once a dungeon, marks the main entrance to the upper fortress.
• Roman Well: A mysterious 60-metre deep shaft with a spiral staircase, dating to the 18th century Austrian reconstruction.
• Outdoor Military Exhibits: Tanks, cannons, and artillery pieces line the fortress walls, creating an open-air display of Serbia's military history.

History

The earliest fortifications date to Celtic and Roman times, when the settlement was known as Singidunum. The Ottomans captured the fortress in 1521 and held it for most of the next three centuries. After Serbian independence, Prince Mihailo Obrenović negotiated the withdrawal of the Ottoman garrison in 1867.

• Tip 2: The fortress grounds are free and open 24 hours; individual museums inside have separate tickets and hours.
• Duration: 1.5–2.5 hours.
