Sofia Art, Architecture & Culture: the back story

About Sofia Art, Architecture & Culture: the back story

By the ULTIMATE Sofia Editorial Team

Editor-in-Chief: Jai Michael

Few capitals let you walk through so many centuries in a single afternoon. In Sofia a Roman street runs beneath a 1950s square, an Ottoman mosque faces a medieval church, icons glow in a cathedral crypt and a former heating plant has become one of the liveliest arts centres in the Balkans. Here is the story, and how to enjoy it.

Serdica beneath your feet

Sofia’s story begins underground. When the metro was dug beneath the Largo, archaeologists uncovered a whole quarter of Roman Serdica: streets, houses, baths and an early Christian church. Today the Ancient Serdica Complex lets you walk among them, open to the sky and partly under glass, between the Sveta Nedelya Cathedral and the Banya Bashi Mosque.

Around it, within a few minutes’ walk, stand the red-brick Rotunda of St George, the Banya Bashi Mosque, the Sofia Synagogue and the Central Mineral Baths, now home to the Sofia History Museum. It is one of the most remarkable crossroads of faiths and eras in Europe, and the best way to understand the city.

In Sofia, the metro station is also an archaeological site: step off the escalator and you are walking on Roman Serdica.

A few streets away, the National Archaeological Museum fills the domed halls of the Great Mosque, built in the 15th century, with treasures from every era of Bulgaria’s past, from Thracian gold to Roman statues and medieval art. Read our story of Thracian gold before you go.

Domes and icons

The golden domes of St Alexander Nevsky Cathedral rise over the centre, the symbol of Sofia. Built between 1882 and 1912 to designs by the Russian architect Alexander Pomerantsev, as a memorial to the soldiers who died in the war of 1877–78, its neo-Byzantine interior glows with frescoes, mosaics, marble, onyx and alabaster.

Beneath it, the crypt holds the National Gallery’s Museum of Christian Art, with one of the finest collections of Bulgarian icons, from the Middle Ages to the 19th century. Behind the cathedral, Square 500, named after its address, shows the National Gallery’s collections of Bulgarian and world art in a grand building on the square.

The icon painters of the National Revival, above all Zahari Zograf of Samokov, carried this art into the 19th century; his immersive exhibition at Square 500 runs until 30 January 2027. Pair it with the frescoes of the medieval Boyana Church on the slopes of Vitosha, a UNESCO World Heritage Site.

The theatre and the opera

Facing the City Garden, the red-and-white Ivan Vazov National Theatre, designed by the Viennese architects Fellner and Helmer, opened in 1906 and is still Bulgaria’s leading stage. Rakovski Street, the city’s theatre street, holds the Salza i Smyah and the Bulgarian Army Theatre, and the National Opera and Ballet is a short walk away.

Bulgaria has given the world an astonishing number of great opera singers, from the bass Boris Christoff to the sopranos of today, and an evening at the National Opera and Ballet is one of Sofia’s great pleasures. Bulgaria Hall, home of the Sofia Philharmonic, completes the classical picture with symphonic and chamber concerts through the season.

The 20th-century city

Sofia was badly damaged by bombing in 1943–44, and much of the centre was rebuilt on a monumental scale. The Largo, the ensemble of three great buildings around the square between Sveta Nedelya and the Presidency, dates from the 1950s and is now admired as architecture in its own right.

At the far end of Vitosha Boulevard, the National Palace of Culture, NDK, opened in 1981 as one of the largest congress and culture centres in South-East Europe, with a long park of fountains in front. It hosts concerts, film festivals and exhibitions, and its Lumière cinema is a favourite with film lovers.

The National Gallery also runs the Museum of Art from the Socialist Period in Izgrev, where sculptures and paintings of the era are shown in a park and gallery as part of the country’s art history, and the Sofia Arsenal Museum of Contemporary Art on Cherni Vrah Boulevard.

Contemporary Sofia

The most exciting new address is Toplocentrala, behind NDK. Built to heat the National Palace of Culture, it began work in 1981 and stood empty from 1983. In 2014 it was chosen as the site for a contemporary arts centre, a design by Bulgarian architects won an international competition in 2018, and the centre opened in 2021 with seven indoor and outdoor spaces for performance, exhibitions, workshops and concerts.

Independent spaces keep the scene young. Swimming Pool, a non-profit project space founded in 2015, meets on a central rooftop with an empty swimming pool; +359 Gallery shows contemporary art in the Water Tower in Lozenets; and the Sofia City Art Gallery in the City Garden holds a large collection of Bulgarian art with changing exhibitions.

Cultural calendar

The Sofia International Film Festival celebrated its 30th edition from 12 to 31 March 2026. Its 31st edition will take place from 11 to 21 March 2027 in Sofia, with further screenings in Plovdiv, Burgas and Varna to the end of March.

At Toplocentrala, the centre marks five years with a Daniel Avery DJ set on 21 November 2026, and ACT FEST 2026 brought independent theatre in October. Always check the official websites before you travel: programmes are announced there first.
