Layered with Roman, Byzantine, medieval Serbian, Ottoman, and Austro-Hungarian history, it is an open-air museum with free entry. Ordered by recommended visit sequence from the main entrance inward and then down to the Lower Town. Allow 3–4 hours for a full visit.

The main entrance into the Upper Town of the fortress, still bearing its Turkish Ottoman name — 'Stambol' being the Serbian form of Istanbul. It was here, in 1867, that the Ottoman commander ceremonially handed the keys of the city to Serbian Prince Mihailo Obrenović, ending centuries of Ottoman presence in Belgrade. Just above the gate stands the Clock Tower (Sahat Kula), built during the Austrian period but completed under Ottoman rule — its name also preserved in Turkish. Fun fact: when control of Belgrade formally passed from the Ottomans to Serbia, the keys were delivered right at this gate's threshold — a moment Serbian schoolchildren still learn about today as one of the most symbolic scenes in national history.

Located in the Upper Town just past the Stambol Gate, this large museum covers Serbian and Yugoslav military history from antiquity to the 20th century. The outdoor courtyard is lined with tanks, artillery pieces, cannons, and aircraft — a free spectacle even without entering. Inside are weapons, uniforms, and maps tracing every major conflict fought on this territory. Fun fact: among the exhibits is a fragment of the American Lockheed F-117 Nighthawk stealth aircraft shot down by Serbia during the 1999 NATO bombing — displayed with the now-legendary Serbian slogan 'Sorry, we didn't know it was invisible.'

One of the best-preserved medieval gates in the fortress, dating back to the 15th century when Belgrade was the capital of the Serbian Despotate under Stefan Lazarević. The word 'zindan' means dungeon in Turkish, reflecting its later use as a prison under Ottoman rule. It features two massive cylindrical towers and a distinctive crown-shaped roof added during a 1938 Romanticist restoration. Fun fact: this gate was one of the key defensive points during the famous 1456 Siege of Belgrade, when Hungarian commander John Hunyadi and his forces — including the friar Giovanni da Capistrano leading an army of peasant crusaders — repelled Mehmed the Conqueror's massive Ottoman army, an outcome that stunned all of Europe.

Despite its name, this is neither Roman nor a well — it is a medieval underground cistern and dungeon dating to the 15th century, dug into the rock during the reign of Despot Stefan Lazarević. The octagonal shaft descends about 40 metres and was used as a prison; enemies and captives were thrown into it and left to die. It is one of the most atmospheric and eerie sights in the fortress. Fun fact: the 'Roman' label was mistakenly applied in the 18th century when Austrians assumed anything old and underground in Belgrade must have been built by the Romans — a classic case of historical wishful thinking that the name has never shaken off.

The most iconic landmark in Belgrade — a towering 14-metre bronze nude male figure by celebrated sculptor Ivan Meštrović, holding a falcon (peace) in one hand and a sword (war) in the other. It stands on the highest point of the fortress walls, looking out over the confluence of the Sava and Danube rivers. Cast in 1913 to commemorate Serbia's victories in the Balkan Wars, it was finally erected here in 1928. Fun fact: the statue was originally meant to stand in a grand fountain on Terazije Square in the city centre, but outraged Belgrade citizens objected to its full nudity being displayed in public — so it was banished to the fortress walls, where the sheer height of the pedestal now makes the nudity harder to notice from street level.

The great ramparts at the western tip of the Upper Town offer the most spectacular panoramic viewpoint in all of Belgrade: from here you can see the confluence of the Sava and Danube rivers, the vast Pannonian Plain stretching to the north, the modern skyline of New Belgrade (Novi Beograd), and on clear days the distant Fruška Gora mountains. These walls have been destroyed and rebuilt over 40 times across history. Fun fact: sunset from this spot is so legendary that Belgradians have a dedicated ritual for it — gathering here with cans of beer and grilled meat in summer, creating an unofficial nightly social event that locals cherish as much as any formal attraction.

A striking Art Deco monument erected in 1930 to honour France's support of Serbia during World War I — France was Serbia's most important ally, and tens of thousands of French soldiers died on the Salonika Front. The monument, created by sculptor Ivan Meštrović and architect Slobodan Jovanović, features two female figures. Fun fact: this monument stands on the exact spot where a monument to the Serbian revolutionary leader Karađorđe (Black George) once stood — which the occupying Austro-Hungarian forces melted down during WWI to recast as a statue of Emperor Franz Joseph. That statue was intercepted by Serbian forces in 1918 and subsequently melted into three church bells — the largest of which still rings in the Ružica Church nearby.

A small, ivy-covered Orthodox church nestled into the fortress wall on the slope between the Upper and Lower Town, most likely originating in the medieval period during Despot Stefan Lazarević's reign (1402–1427). Rebuilt multiple times, it was most recently restored in 1921–1925 after near-total destruction in WWI, with the design by Russian émigré architect Nikolay Krasnov. Its chandeliers are famously made from bullet casings, rifle parts, and bayonets collected from the WWI battlefields — transforming weapons of war into sources of light. Fun fact: the bell currently ringing in Ružica's tower was cast from the bronze of the Franz Joseph statue intercepted from the Austro-Hungarian forces in 1918 — making it literally a converted instrument of occupation.

A modest modern Orthodox chapel just below the Ružica Church, built in the 1930s by architect Momir Korunović on the site of a much older chapel dedicated to Parascheva of the Balkans (Saint Petka). Adjacent to the chapel is a spring whose waters are believed by locals — and pilgrims of all faiths across centuries — to have healing properties, particularly for eye ailments. Fun fact: during the medieval period, the spring was so revered that Muslim, Catholic, and Orthodox Christians all made pilgrimages to it — a remarkable example of interfaith devotion at what was often one of Europe's bloodiest flashpoints.

The only surviving medieval tower of the Belgrade Fortress, built around 1460 by the Hungarians as the main defensive watchtower protecting the Danube port of the Lower Town. Its name means 'fearless' in Serbian. After the Ottoman reconquest it became a notorious dungeon — prisoners were strangled and thrown through openings into the Danube. Its most famous captive was Greek revolutionary poet Rigas Feraios, strangled here by the Ottomans in 1798, who is revered today as a proto-martyr of Greek independence. Since 2010 it operates as a museum dedicated to his memory. Fun fact: the very first leather football brought to Serbia is also linked to this tower's history — Hugo Buli, whose father was imprisoned here, was the student in Berlin who smuggled the first football into the country in 1896.

One of the most uniquely situated zoos in Europe — located entirely within the walls of a medieval fortress. Founded in 1936, it houses over 2,000 animals across 270 species including big cats, primates, bears, giraffes, and reptiles, all within enclosures integrated into the ancient ramparts and moat. Fun fact: the zoo's poetic Serbian name, 'Bašta dobre nade' (Garden of Good Hope), was chosen as an optimistic counterweight to its fortified, once-militaristic surroundings — a deliberate gesture of peace and nature in what had long been a place of war.
