Top 10 Castles in Serbia

Serbia was at the crossroads of the competing medieval empires — Byzantine, Bulgarian, and Serbian — and then the frontier between the expanding Ottoman Empire and the Habsburg defence line for three centuries. The fortifications that resulted are remarkable in their variety: Byzantine-period hilltop citadels, Serbian Empire towers, and the Danube frontier fortresses that defined the most contested military boundary in 15th-century Europe. These ten are the most significant. Find them on the map.

1. Belgrade Fortress (Beogradska Tvrđava), Belgrade

Belgrade Fortress, at the confluence of the Sava and Danube rivers, has been a defended position since the Celts, through Roman, Byzantine, Bulgarian, Hungarian, Serbian, Ottoman, and Habsburg periods. The current structure — a complex of walls, towers, and gates on the Kalemegdan promontory above the rivers — is primarily Ottoman (18th century) on earlier foundations. The Kalemegdan park surrounding the fortress is the most visited public space in Belgrade.

2. Smederevo Fortress

Smederevo, on the Danube 45 kilometres southeast of Belgrade, is the largest medieval fortress in Serbia and one of the largest in the Balkans. Built by the Serbian despot Đurađ Branković from 1428-30 as his capital after Belgrade was ceded to Hungary, it encloses approximately 11 hectares with walls 5 kilometres in circuit. The city within the walls was once the largest populated fortress in Europe. Ottoman forces took it in 1459, ending the Serbian medieval state.

3. Golubac Castle, Braničevo

Golubački grad — Golubac Castle — on a narrow Danube cliff near the Iron Gates gorge, is the most dramatically sited medieval fortress in Serbia. The nine towers rising from the cliff above the Danube, built in the 14th century by Serbian and later Hungarian and Ottoman occupiers, form one of the most striking silhouettes of any Balkan fortress. The site was substantially restored in the early 21st century.

4. Petrovaradin Fortress, Novi Sad

Petrovaradin, above the Danube at Novi Sad, is a Vauban-style fortress of extraordinary scale built by the Habsburgs from the 1690s. The underground tunnel system — 16 kilometres of galleries on four levels — is the most extensive military underground network in the Balkans. The annual EXIT music festival, one of the largest in Europe, is held in the fortress each July.

5. Maglič Fortress, Raška

Maglič, above the Ibar river in central Serbia, is a well-preserved 13th-century fortress of the Serbian medieval state. The cylindrical towers and enclosing wall, built by the Nemanjić dynasty, survive to substantial height; the site's isolation in a river canyon has preserved it from the stone-robbing that has reduced many medieval Serbian fortresses.

6. Niš Fortress

Niš Fortress, in the centre of Niš, is an Ottoman fortress of the early 18th century built on the site of earlier Roman and Byzantine fortifications. The four-bastioned plan, with a gate complex on each side, encloses a large area of the city; the Skull Tower (Ćele Kula), built from the skulls of Serbian rebels after the First Serbian Uprising of 1809, stands outside the fortress walls.

7. Soko Grad (Falcon City), Sokobanja

Soko Grad, above the spa town of Sokobanja in eastern Serbia, is a medieval fortress of the Branković family with spectacular views over the Moravian plain. The upper castle's position on a sheer rock and the lower castle's defensive walls form a typical Serbian medieval fortification arrangement.

8. Sokolac Fortress, Brvenica

Sokolac, above the Ibar valley near Brvenica in central Serbia, was the seat of the Serbian nobility in the period of Ottoman expansion. The fortress, on a difficult rocky height, provided the final refuge of the local lords as the Ottoman frontier advanced through the 15th century.

9. Ram Fortress

Ram, on the Danube opposite the Romanian fortress of Turnu (now lost), was an Ottoman frontier fortress of the 15th century controlling the river at a strategic narrows. The triangular plan with round towers is well preserved; the riverside position provides views over the Romanian side of the Iron Gates.

10. Grad Stalać, Stalać

Stalać, at the confluence of the Western and Southern Morava rivers, was a key Serbian medieval fortress controlling the confluence and the routes into the interior. The ruins, spread over the confluence hill, represent the typical Serbian medieval fortification form of the 14th-15th century.
