Things to do in Sofia: step inside Alexander Nevsky Cathedral with its golden domes, go down into the crypt of Saint Sofia Basilica, see the Rotunda of St. George and the Roman ruins of Serdica among the buildings, walk the « triangle of tolerance » (mosque, synagogue, cathedrals), stroll up Vitosha Boulevard, then head for the frescoes of Boyana Church and the trails of Mount Vitosha. Allow 2 to 3 days, plus Rila Monastery; the best months are May to September.

Completed in the early 20th century in tribute to the Russian soldiers who died in the 1877-1878 war of liberation, it is one of the largest Orthodox churches in the Balkans. Its golden domes dominate the city; the dark interior is covered with frescoes and chandeliers. The crypt holds a collection of icons. An antiques market often sets up on the square.
Saint Sofia Basilica
Right opposite, this 6th-century brick basilica gave the city its name. Beneath the nave, an underground route leads through a necropolis with painted tombs from late antiquity. Next door is the Tomb of the Unknown Soldier.
The Rotunda of St. George and the ruins of Serdica
In a courtyard surrounded by the presidency buildings, the red-brick Rotunda of St. George is the oldest building still standing in Sofia; it preserves medieval frescoes. Around it, and in Serdica metro station, the remains of the Roman city of Serdica (streets, baths) are visible in the open air. The changing of the guard takes place in front of the presidency.
The « triangle of tolerance »
A few hundred meters apart stand the Ottoman-era Banya Bashi Mosque, Sofia Synagogue, one of the largest in Europe, St. Joseph’s Catholic Cathedral and the Orthodox Church of St. Nedelya. The former Central Mineral Baths, with Secession-style decoration, house the Sofia History Museum; in front, hot mineral water fountains let locals fill their bottles. The Central Market Hall is just opposite.
The Russian Church and Vitosha Boulevard
The small, colorful Russian Church of St. Nicholas, with its golden onion domes, is one of the most photographed in the city. Pedestrianized Vitosha Boulevard is lined with cafés, restaurants and shops up to the National Palace of Culture (NDK), with the mountain as a backdrop. The garden of the Ivan Vazov National Theater is a favorite local resting spot.
Boyana Church and the National History Museum
At the foot of Vitosha, Boyana Church, a UNESCO World Heritage Site, preserves frescoes from 1259 of striking realism for their time; visits are in small groups, for a few minutes. Nearby, the National History Museum, housed in the former government residence, displays Thracian gold treasures among other collections.
Mount Vitosha
The massif overlooking the city peaks at over 2,200 m (7,218 ft) at Cherni Vrah. From the center, buses or taxis reach the trailheads at Zlatni Mostove (a « stone river ») or the Aleko area, which also has a small ski area in winter. Half a day is enough for a first walk, such as to Boyana Waterfall.
Rila and Plovdiv day trips
Rila Monastery, the most famous in the country and UNESCO-listed, is about two hours’ drive south: a day trip, often combined with Boyana. Plovdiv, with its Roman theater and old town, is about two hours away by road or train. See our Bulgaria travel guide.
