About Sofia

Sofia became the capital of Bulgaria in 1879, one year after Bulgaria gained autonomy from the Ottoman Empire following the Russo-Turkish War of 1877-1878. The city had been under Ottoman rule for nearly 500 years, from 1382 until the Russian military victory freed it in January 1878. Sofia was chosen as the capital over Tarnovo, the seat of the medieval Bulgarian Empire and the site of the constitutional assembly, partly because of its more central geographic position and its existing infrastructure. Bulgaria was the first Slavic state to adopt a written constitution, the Tarnovo Constitution of 1879. During the Cold War, Sofia was the capital of the People's Republic of Bulgaria, a Soviet-aligned communist state from 1946 to 1989. Bulgaria transitioned to democracy following the fall of communism in November 1989 and joined NATO in 2004 and the European Union in 2007. The National Assembly, the Council of Ministers, and the presidency are all located in central Sofia.

About Bulgaria

Bulgaria is a parliamentary republic in which the prime minister holds executive power and the president has a largely ceremonial role. Bulgaria joined NATO in 2004 and the EU in 2007. It has experienced significant political instability, with multiple snap elections in the early 2020s. Bulgaria is a candidate to join the eurozone but has faced delays due to inflation criteria not being met consistently.

Frequently Asked Questions

  • Why is Sofia the capital of Bulgaria and not Tarnovo?

    Sofia was chosen as Bulgaria's capital in 1879 over Tarnovo, the historical capital of the medieval Bulgarian Empire, primarily due to its more central geographic location within the newly autonomous Bulgarian territory. Tarnovo had hosted the constitutional assembly that drafted the Tarnovo Constitution but was seen as peripheral to the western Bulgarian lands. Sofia's existing infrastructure also played a role in the decision.

  • When did Bulgaria gain independence from the Ottoman Empire?

    Bulgaria gained autonomy as a principality in 1878, following the Russo-Turkish War of 1877-1878 and the Treaty of Berlin. Full independence from the Ottoman Empire was declared in 1908 by Prince Ferdinand. Sofia had been captured from Ottoman forces by the Russian army in January 1878, ending nearly 500 years of Ottoman rule over the city.

  • How long was Sofia under Ottoman rule?

    Sofia was under Ottoman rule from 1382, when Ottoman forces captured the city, until January 1878, when the Russian army liberated it during the Russo-Turkish War, a period of approximately 496 years. During this time, the city was known as Sofya and served as an important administrative centre in the Ottoman Empire's Balkan territories.

  • When did Bulgaria join the EU and NATO?

    Bulgaria joined NATO on 29 March 2004 and became a member of the European Union on 1 January 2007. Both accessions were part of the broader expansion of Western institutions into Central and Eastern Europe following the end of the Cold War. Bulgaria had been a communist state aligned with the Soviet Union from 1946 until the democratic transition in 1989.

  • Is Sofia the largest city in Bulgaria?

    Yes. Sofia is Bulgaria's largest city by a significant margin, with approximately 1.4 million residents in the city proper and around 1.7 million in the metropolitan area. Bulgaria's second city, Plovdiv, has approximately 350,000 residents. Sofia accounts for a substantial share of the country's total economic output and population.

Sights and landmarks

The Alexander Nevsky Cathedral from 1912, with its golden domes, is one of the largest Orthodox cathedrals in the Balkans and can hold up to 10,000 worshippers. The Boyana Church, on the UNESCO World Heritage List since 1979, contains frescoes from 1259 that are considered precursors of the Italian Renaissance. The Saint Sofia Church from the 6th century gave the city its name. The National Historical Museum in Boyana houses the Panagyurishte Treasure, a Thracian golden find from the 4th century BC. The Vitosha Mountain, with a peak of 2,290 metres, lies directly south of the city.

Climate and best time to visit

Sofia has a humid continental climate (Dfb) moderated by its location at 550 metres elevation. January averages between -4 and 3 degrees Celsius, July between 14 and 27 degrees. Annual precipitation is around 580 millimetres, with most rain in May and June. Snowfall is common from December to February. The best travel period is May to October for city visits, and December to March for ski tourism on Vitosha.

Regional significance

Sofia is one of the oldest cities in Europe, continuously inhabited for around 7,000 years. The city bore the name Serdica under the Romans, and Emperor Constantine the Great called it my Rome. Sofia sits on a plateau at 550 metres, surrounded by the Vitosha mountain range, making it one of Europe's highest-lying capitals. Bulgaria joined the Schengen Area for air and sea travel in 2024, and from 1 January 2025 also for land travel, better integrating Sofia into the European travel infrastructure.

Culture and customs

Sofia is culturally influenced by five centuries of Ottoman rule, followed by a strongly Russian-oriented communist era. The Bulgarian Orthodox Church is dominant (around 80 percent of the population). The cuisine combines Balkan and Mediterranean influences with shopska salad (cucumber, tomato, cheese), banitsa (filo pastry) and tarator (cold yoghurt soup). Bulgaria is world-famous for rose oil from the Valley of Roses, accounting for around 70 percent of global production. Cyrillic script originated in the First Bulgarian Empire in the 9th century and is an important cultural export.

Economy

Sofia generates around 40 percent of Bulgaria's GDP and is the main centre for IT, finance and outsourcing. The city hosts regional headquarters of companies such as HP, IBM, SAP, VMware and Coca-Cola. The IT sector employs more than 50,000 workers and grows annually at double-digit rates, stimulated by a flat tax of 10 percent on corporate income, the lowest in the EU. Sofia Tech Park, opened in 2015, is the country's first publicly funded technology park.
