Stand on the ridge at Kalemegdan where the Sava meets the Danube and the whole shape of Belgrade becomes clear: a fortress on a bluff, a pedestrian street running south from it, and a city that has been rebuilt more times than most. The rivers are the constant; everything else has changed hands.
Belgrade suits travellers who like their cities layered and a little rough-edged, who are happy to walk between an Ottoman mosque, a 19th-century cathedral and a museum of illusions in the same afternoon. It rewards curiosity more than checklist-ticking.
This guide covers the sights of Stari Grad and mid-town that you can realistically reach on foot, with a one-day plan at the end that strings the best of them together.
Top things to do in Belgrade
1. Kalemegdan
Kalemegdan is the fortress, park and earliest settlement of Belgrade, sitting on a bluff above the confluence of the Danube and Sava. It is free to access around the clock, and within its bounds you will find the Military Museum, a couple of churches and a zoo, so it can absorb as much time as you give it.
Give it a half-day rather than an hour. The Military Museum inside the fortress has an extensive collection of Serbia's military history with good signage in English, and is open Tuesday to Sunday.
2. Kneza Mihaila
Kneza Mihaila is the main pedestrian street, lined with elegant 19th-century buildings and running south from Kalemegdan to Republic Square. It is the natural spine of a walking day in Stari Grad, and several of the sights below sit directly on or just off it.
Walk it in one direction rather than doubling back, and treat the side streets as part of the route. Heritage House, next to the Zepter Museum, hosts changing art exhibitions.
3. National Museum
The National Museum stands on Republic Square, entered from the side street Vase Čarapića. It was founded in 1844 and holds more than 400,000 items across three floors, organised into Paleolithic, Ancient History, Middle Ages and Modern sections.
It is free on Sundays, which is worth knowing if you are planning your week around it. Pair it with Republic Square itself, which fronts the museum's south side and holds the equestrian statue of Prince Mihailo Obrenović.
4. Belgrade Cathedral
The Cathedral Church of St Michael the Archangel is Orthodox, built between 1837 and 1840 in neoclassical style with a richly decorated interior. Two notable Serbian linguists, Vuk Karadžić and Dositej Obradović, are buried in front of the church, and entry is free.
Directly opposite is the Museum of the Serbian Orthodox Church, which holds frescoes, mosaics and icons with good English signage. A short walk away on the same street is the Residence of Princess Ljubica, built in 1830 and now a branch of the City Museum showing 19th-century architecture and furnishings.
5. Church of Saint Sava
The Church of Saint Sava is one of the largest Orthodox church buildings in the world, and it dominates the view as you walk south along Terazije. Terazije is the spine boulevard, becoming Kralja Milana at the Old Palace, and the church is the landmark that pulls you down it.
Use the walk south as the point of the trip rather than a means to an end. The boulevard is lined with grand buildings, and the police will shoo you away from several of them, so keep to the public pavement.
6. Nikola Tesla Museum
The Nikola Tesla Museum on Krunska is devoted to Tesla (1856–1943). It opens at 10:00 daily, closing at 18:00 on Mondays and 20:00 the rest of the week.
It sits in the mid-town cluster, so combine it with the Historical Museum of Serbia on Nikole Pasica and the National Assembly nearby rather than making a separate trip.
7. Ethnographic Museum
The Ethnographic Museum on Studentski trg holds an extensive display of Serbian costumes, tools, culture and everyday life in past centuries. It is closed on Mondays.
Between the Ethnographic Museum and the Bajrakli Mosque you will find the Vuk & Dositej Museum at Gospodar-Jevremova 21, a branch of the National Museum with the same hours, showing the development of the Serbian language. The two make a natural pair.
8. Bajrakli Mosque
Bajrakli Mosque on Gospodar Jevremova was built around 1575, when Islam was the majority religion, and is now the only mosque in Belgrade. Its name means "with flag": the muwaqqit calculated the exact time of Islamic observances and hoisted a flag to advise the other city mosques, whereupon each muezzin called from their minaret to those within earshot.
It has been damaged several times, most recently in 2004, and restored. Entry is free and it is accessible at all hours.
9. Zepter Museum
The Zepter Museum on Kneza Mihaila shows modern Serbian art. It opens at 12:00 Tuesday to Friday and at 10:00 on Saturday and Sunday, closing at 20:00 throughout.
Because it sits on the pedestrian street, it slots easily into a walking day between Kalemegdan and Republic Square. Heritage House is right next door if you want a second exhibition in the same stop.
10. St Mark's Church
St Mark's Church on Bulevar Kralja Aleksandra, in Tašmajdan Park, is a large Serbian Orthodox church built between 1931 and 1940 in Serbo-Byzantine style. Within are the tombs of King Stefan Uroš IV Dušan and of King Aleksandar I Obrenović and his Queen Draga Mašin.
Next door, dwarfed by St Mark's, is the Church of the Holy Trinity, Russian Orthodox, built in 1924 for White Russians fleeing after their civil war. Opposite St Mark's at Ruzveltova 54 is the Museum of Roma Culture.
11. Historical Museum of Serbia
The Historical Museum of Serbia on Nikole Pasica holds a huge collection of materials about the Serbian nation from ancient times to the present. It opens at 12:00 and closes at 20:00, Tuesday to Sunday.
Note that it is intended to move in coming years to new premises on the site of the former railway station, so check before you build a day around it. The National Assembly, a grand neo-baroque legislative palace, is on the same square.
12. Ružica church and Sveta Petka
Ružica church within the fortress dates to the 15th century, was destroyed in the 18th century, rebuilt, and destroyed again in World War I. The present version was created in 1925, embellished with bronze soldier guards in front and unusual chandeliers made from bullet shells, swords and bayonets. The name means "little rose", though it is clad in ivy.
Sveta Petka is a chapel next to Ružica, built in 1937. Both are inside Kalemegdan, so see them as part of your fortress visit rather than a separate stop.
13. Museum of Science and Technology
The Museum of Science and Technology on Skenderbegova covers gadgets, transport and machinery down the ages. It is open Tuesday to Sunday.
It sits in Dorćol, the neighbourhood running from the mosque down the slopes north to the Danube riverbank. The name is Turkish, from dort yol, meaning "four roads" or a crossroads, though the area was rebuilt in Austrian style from 1717. The west end looks prosperous; the east end is grubby and industrial, being a busy river port.
14. Church of St Alexander Nevsky
The Church of St Alexander Nevsky on Cara Dušana was completed in 1929, replacing an earlier church of 1877. It has notable relics and frescoes and is open daily.
It sits in the same Dorćol stretch as the Museum of Science and Technology, so the two combine well on a walk down towards the river.
15. Museum of Illusions
The Museum of Illusions on Nušićeva is a family-friendly place with the fairground usuals: distorting mirrors, an Ames Room and so on. It is open daily from 09:00 to 21:00.
It is a good wet-afternoon or end-of-day option in mid-town, and the Museum of the Paranormal on Lomina is nearby if you want to keep going in the same vein.
If you only have one day
Morning. Start at Kalemegdan, which is free and open around the clock. Walk the fortress and park, and take in Ružica church and Sveta Petka while you are inside the walls. If military history interests you, the Military Museum is open from 10:00.
Afternoon. Come down onto Kneza Mihaila and walk it south, stopping at the Zepter Museum and then the National Museum on Republic Square. From there, follow Terazije south towards the Church of Saint Sava, which dominates the view the whole way.
Evening. Head back into Stari Grad for the Belgrade Cathedral, free to enter, and the Bajrakli Mosque on Gospodar Jevremova, which is accessible at all hours. If you still have energy, the Museum of Illusions stays open until 21:00.
