Yellow paving stones run underfoot along the streets of central Sofia, laid in the early 20th century and still adding colour to the administrative heart of the city. Walk a few blocks and the skyline shifts from the domes of St. Alexander Nevsky Cathedral to the minaret of Banya Bashi Mosque to the facade of the Sofia Synagogue, three temples of three faiths within two blocks of each other.
Sofia suits travellers who like their history layered and their sightseeing compact: Roman ruins sit in the geographical centre of the city, communist-era statues stand in an open-air park, and the Vitosha mountain rises at the southern edge for a half-day escape. This guide covers the museums, churches, monuments and historic buildings worth your time, followed by a one-day plan that strings the best of them together.
Top things to do in Sofia
1. St. Alexander Nevsky Cathedral
The largest church in the Balkans, built to honour the Russian soldiers who died during the Russo-Turkish War of 1877–1878, which liberated Bulgaria from Ottoman rule. It stands on Alexander Nevsky Square and can hold 5,000 worshippers.
Combine it with the National Art Gallery collections at National Gallery Square 500, which sit at the same square and are open Tuesday to Sunday, closed Mondays and holidays.
2. St. Sophia Church
Built in the 6th century in the same wave of construction as the Hagia Sophia in Constantinople, this church gave its name to the city in 1329. It was destroyed several times and served as a mosque during Ottoman rule, and it was built over an even older 4th-century church whose excavated crypts and tombs you can explore.
It is across the square and to the right from St. Alexander Nevsky Cathedral, so the two fit naturally into one visit.
3. Boyana Church
This small 11th-century church and garden is on the UNESCO World Heritage List for its well-preserved murals. The layer of fresco from 1259 shows a realism and emotion evocative of the early Renaissance, painted a century earlier.
Only eight people are permitted inside at a time, for a maximum of ten minutes, and no photos are allowed inside. During busy periods you may wait over an hour, so arrive early and be prepared to stand outside. To get there, take bus 64 from metro station Vitosha to the Boyana Church stop. The church sits at the foot of Vitosha mountain and is a good starting point for day trips in the mountain.
4. Sofia History Museum
Housed in the colourful old building of the Central Mineral Baths, built in 1913, this museum covers the history of Sofia itself. Exhibits include many luxurious items that formerly belonged to Bulgaria's last monarchs.
Entry is 10 лв. The building's mineral-spring heritage makes it a natural pairing with the surrounding central sights.
5. Regional History Museum of Sofia
Behind Banya Bashi Mosque at 1 Banski Sq, this museum is open Tuesday to Sunday from 10:00 to 18:00. Its position puts it directly beside the mosque and within the cluster of religious buildings in the centre.
Visit on the same stop as Banya Bashi Mosque and the Sofia Synagogue to see the "triangle of religious tolerance" in one walk.
6. National Museum of History
In the Rezidentsia Boyana, this museum offers a comprehensive view of Bulgarian history from prehistory to the present in as broad a European context as possible. Among the main attractions are golden and silver mugs and jewellery from the Thracian and Roman periods, and about half of the exhibits have English captions.
It is open 09:30–18:00 and entry is 10 лв, or 1 лв for students. To reach it, take trolley #2 to the roundabout at the end of the bus line, cross the ring road and walk through the trees; the museum is not visible from the road and there are no signs, so keep an eye out. Allow several hours.
7. Museum of Socialist Art
After the fall of the Soviet Union and Bulgaria's move away from communism, much of the country's communist artwork was collected here. Outside the museum, and free to access, is a small park filled with statues of notable communists.
The museum is open Tuesday to Sunday, 10:00–18:00. The outdoor park means you can see part of the collection without paying.
8. Amphitheatre of Serdica
Roman ruins sit in the geographical centre of the city, under the flags of the EU. Sofia is one of the oldest cities in Europe and has ancient ruins throughout the city centre, and this amphitheatre is the one embedded in the modern street layout.
It is central enough to fold into a walking route between the mosque, synagogue and church cluster.
9. Banya Bashi Mosque
A beautiful yet simple Ottoman mosque built by Mimar Sinan. It is active, and there is a guide inside.
The Regional History Museum of Sofia is directly behind it, and the Sofia Synagogue is within the same two-block cluster, so all three can be seen together.
10. Sofia Synagogue
One of the largest synagogues in Europe, open 09:00 to 16:30. It forms the third point of the city's "triangle of religious tolerance", alongside Sveta Nedelya Church and Banya Bashi Mosque.
Pair it with the mosque and the Catholic cathedral St. Joseph, which is next to the Sheraton Hotel, to complete the expanded "square" of religious tolerance.
11. National Museum of Natural History
At 1 Tzar Osvoboditel Blvd, this museum has four floors of everything from rocks and minerals to insects and stuffed bison. It is open 10:00–18:00.
It is a good way to spend a rainy afternoon, and its position on Tzar Osvoboditel Blvd places it near the National Art Gallery and the city centre.
12. Earth and Man National Museum
A large mineralogical museum at 4 Cherni Vruh Blvd, open 10:00–18:00. In the main hall is the world's biggest collection of giant crystals, with jagged rocks the size of refrigerators.
It is a focused stop rather than a whole afternoon, and works well combined with other central sights.
13. National Museum of Military History
At 92 Cherkovna Str, this is the only museum in Bulgaria with four types of exhibitions: open air, chronological, collections and temporary. It holds over 28,000 exhibits dated from antiquity to the present day, and its open-air exhibition is the largest on the Balkans, with over 300 pieces of military equipment.
It is open 10:00–18:00. The collections of weapons, uniforms, decorations, art works, flags, photographs and military equipment reward a longer visit.
14. The Red Flat
At 24 Ivan Denkoglu Str, this is half tour, half experience: you walk around a house set up like an old communist flat from the 1980s. You are allowed to touch and play with just about anything, and there is an audio guide in English, Spanish and Bulgarian.
It is open daily 10:30–19:30. Its central address makes it easy to slot between other sights.
15. Monument to Vasil Levski
This monument commemorates the hanging of Bulgarian national hero and major revolutionary figure Vasil Levski in the city on 18 February 1873.
It is a straightforward stop while walking the central streets, and pairs with the other monuments and historic buildings nearby.
If you only have one day
Morning: Start at St. Alexander Nevsky Cathedral on Alexander Nevsky Square, then walk across the square and to the right to St. Sophia Church, where you can explore the excavated crypts and tombs of the older 4th-century church beneath it.
Afternoon: Move into the centre for the cluster of religious buildings: Banya Bashi Mosque, the Sofia Synagogue, and the Regional History Museum of Sofia behind the mosque. Add the Amphitheatre of Serdica, which sits in the geographical centre of the city, and the Sofia History Museum in the old Central Mineral Baths building.
Evening: Finish at the Museum of Socialist Art, open until 18:00, where the outdoor park of communist statues is free to access, or at The Red Flat on Ivan Denkoglu Str, open until 19:30, to walk through a 1980s communist flat.

Winters are relatively cold and snowy, with temperatures that can drop below −15 °C in January, while summers are warm and sunny and can reach or exceed 35 °C on the hottest days, particularly in July and August. Springs and autumns are usually short with variable weather.
How do I get to Boyana Church?
From metro station Vitosha, take bus 64 to the Boyana Church stop, a small plaza with a few shops and a hotel. The church is at the foot of Vitosha mountain and is a good starting point for day trips in the mountain.
Which sights are close enough to see together?
The "triangle of religious tolerance" is the clearest cluster: Sveta Nedelya Church, Banya Bashi Mosque and Sofia Synagogue are situated close together, and the triangle was recently expanded to a "square" including the Catholic cathedral St. Joseph. The Regional History Museum of Sofia is directly behind Banya Bashi Mosque, and St. Sophia Church is across the square from St. Alexander Nevsky Cathedral.
Are there sights outside the city centre worth the trip?
Yes. The National Museum of History in the Rezidentsia Boyana and the Boyana Church both sit away from the centre; the church is reached by bus 64 from metro station Vitosha, and the museum by trolley #2 to the end of the bus line, followed by a walk across the ring road.
