Introduction
Sofia is the capital and largest city of Bulgaria. It is situated in the Sofia Valley at the foot of the Vitosha mountain, in the western part of the country. The city is built west of the Iskar river and has many mineral springs, such as the Sofia Central Mineral Baths. It has a humid continental climate. Known as Serdica in antiquity, Sofia has been an area of human habitation since at least 7000 BC. The recorded history of the city begins with the attestation of the conquest of Serdica by the Roman Republic in 29 BC from the Celtic tribe Serdi. During the decline of the Roman Empire, the city was raided by Huns, Visigoths, Avars, and Slavs. In 809, Serdica was incorporated into the First Bulgarian Empire by Khan Krum and became known as Sredets. In 1018, the Byzantines ended Bulgarian rule until 1194, when it was reincorporated by the Second Bulgarian Empire. Sredets became a major administrative, economic, cultural and literary hub until its conquest by the Ottomans in 1382. From 1530 to 1836, Sofia was the regional capital of Rumelia Eyalet, the Ottoman Empire's largest and most important province. Bulgarian rule was restored in 1878. Sofia was selected as the capital of the Third Bulgarian State in the next year, ushering a period of intense demographic and economic growth. Sofia is the 14th-largest city in the European Union. It is surrounded by mountains including Vitosha to the south, Lyulin to the west, and the Balkan Mountains to the north. It is the third highest European capital after Andorra la Vella and Madrid. Sofia is home to several universities, cultural institutions and commercial companies. The city has been described as the "triangle of religious tolerance". This is because three temples of three major world religions—Christianity, Islam and Judaism—are situated close together: Sveta Nedelya Church, Banya Bashi Mosque and Sofia Synagogue. This triangle was recently expanded to a "square" and includes the Catholic Cathedral of St Joseph. The Boyana Church in Sofia, constructed during the Second Bulgarian Empire and holding much patrimonial symbolism to the Bulgarian Orthodox Church, was included onto the World Heritage List in 1979. With its cultural significance in Southeast Europe, Sofia is home to the National Opera and Ballet of Bulgaria, the National Palace of Culture, the Vasil Levski National Stadium, the Ivan Vazov National Theatre, the National Archaeological Museum, and the Serdica Amphitheatre. The Museum of Socialist Art includes many sculptures and posters that educate visitors about the lifestyle in communist Bulgaria. The population of Sofia declined from 70,000 in the late 18th century, through 19,000 in 1870, to 11,649 in 1878, after which it began increasing. Sofia hosts some 1.28 million residents within a territory of 500 km2, a concentration of 17.9% of the country's population within the 200th percentile of the country's territory. The urban area of Sofia hosts some 1.5 million residents within 5723 km2, which comprises Sofia City Province and parts of Sofia Province (Dragoman, Slivnitsa, Kostinbrod, Bozhurishte, Svoge, Elin Pelin, Gorna Malina, Ihtiman, Kostenets) and Pernik Province (Pernik, Radomir), representing 5.16% of the country territory. The metropolitan area of Sofia is based upon one hour of car travel time, stretches internationally and includes Dimitrovgrad in Serbia. The metropolitan region of Sofia is inhabited by a population of 1.6 million.
History & Origins
The area has a history of nearly 7,000 years, with the great attraction of the hot water springs that still flow abundantly in the centre of the city. The Neolithic village in Slatina dating to the 5th–6th millennium BC is documented. Another neolithic settlement was founded in the 3rd–4th millennium BC near the site of the modern National Art Gallery, which has been the traditional centre of the city ever since. The earliest tribes who settled were the Thracian Tilataei. In the 500s BC, the area became part of a Thracian state union, the Odrysian kingdom from another Thracian tribe the Odrysses. In 339 BC Philip II of Macedon destroyed and ravaged the town for the first time. The Celtic tribe Serdi gave their name to the city. The earliest mention of the city comes from an Athenian inscription from the 1st century BC, attesting Astiu ton Serdon, i.e. city of the Serdi. According to the inscription and to the writings of Dio Cassius, the Roman general Crassus subdued the Serdi and behanded the captives. Dio Cassius, Pliny the Elder and Ptolemy say that in 27–29 BC Crassus attacked the region "Segetike", which is assumed to be Serdica, or the city of the Serdi. The ancient city is located between TZUM, Sheraton Hotel and the Presidency. It gradually became the most important Roman city of the region. It became a municipium during the reign of Emperor Trajan (98–117). Serdica expanded, as turrets, protective walls, public baths, administrative and cult buildings, a civic basilica, an amphitheatre, a circus, the City council (Boulé), a large forum, a big circus (theatre), etc. were built. Serdica was a significant city on the Roman road Via Militaris, connecting Singidunum and Byzantium. In the 3rd century, it became the capital of Dacia Aureliana, and when Emperor Diocletian divided the province of Dacia Aureliana into Dacia Ripensis (at the banks of the Danube) and Dacia Mediterranea, Serdica became the capital of the latter. Serdica's citizens of Thracian descent were referred to as Illyrians probably because it was at some time the capital of Eastern Illyria (Second Illyria). Roman emperors Aurelian (215–275) and Galerius (260–311) were born in Serdica. The city expanded and became a significant political and economical centre, more so as it became one of the first Roman cities where Christianity was recognised as an official religion (under Galerius). The Edict of Toleration by Galerius was issued in 311 in Serdica by the Roman emperor Galerius, officially ending the Diocletianic persecution of Christianity. The Edict implicitly granted Christianity the status of "religio licita", a worship recognised and accepted by the Roman Empire. It was the first edict legalising Christianity, preceding the Edict of Milan by two years. Serdica was the capital of the Diocese of Dacia (337–602). For Constantine the Great it was 'Sardica mea Roma est' (Serdica is my Rome). He considered making Serdica the capital of the Byzantine Empire instead of Constantinople. which was already not dissimilar to a tetrarchic capital of the Roman Empire. In 343 AD, the Council of Sardica was held in the city, in a church located where the current 6th century Church of Saint Sophia was later built. The city was destroyed in the 447 invasion of the Huns and laid in ruins for a century It was rebuilt by Byzantine Emperor Justinian I. During the reign of Justinian it flourished, being surrounded with great fortress walls whose remnants can still be seen today.
Geography & Climate
Sofia City Province has an area of 1344 km2, while the surrounding and much bigger Sofia Province is 7,059 km2. Sofia's development as a significant settlement owes much to its central position in the Balkans. It is situated in western Bulgaria, at the northern foot of the Vitosha mountain, in the Sofia Valley that is surrounded by the Balkan mountains to the north. The valley has an average altitude of 550 metres (1,800 ft). Sofia is the second highest capital of the European Union (after Madrid) and the third highest capital of Europe (after Andorra la Vella and Madrid). Unlike most European capitals, Sofia does not straddle any large river, but is surrounded by comparatively high mountains on all sides. Three mountain passes lead to the city, which have been key roads since antiquity, Vitosha being the watershed between Black and Aegean Seas. A number of shallow rivers cross the city, including the Boyanska, Vladayska and Perlovska. The Iskar River in its upper course flows near eastern Sofia. It takes its source in Rila, Bulgaria's highest mountain, and enters Sofia Valley near the village of German. The Iskar flows north toward the Balkan Mountains, passing between the eastern city suburbs, next to the main building and below the runways of Vasil Levski Sofia Airport, and flows out of the Sofia Valley at the town of Novi Iskar, where the scenic Iskar Gorge begins. The city is known for its 49 mineral and thermal springs. Artificial and dam lakes were built in the twentieth century. While the 1818 and 1858 earthquakes were intense and destructive, the 2012 Pernik earthquake occurred west of Sofia with a moment magnitude of 5.6 and a much lower Mercalli intensity of VI (Strong). The 2014 Aegean Sea earthquake was also noticed in the city.
Sofia has a humid continental climate (Köppen climate classification Dfb; Cfb if with −3 °C isotherm) with an average annual temperature of 10.9 °C (51.6 °F). Winters are relatively cold and snowy. In the coldest days temperatures can drop below −15 °C (5 °F), most notably in January. The lowest recorded temperature is −31.2 °C (−24 °F) (16 January 1893). On average, Sofia receives a total snowfall of 98 cm (38.6 in) and 56 days with snow cover. The snowiest recorded winter was 1939/1940 with a total snowfall of 169 cm (66.5 in). The record snow depth is 57 cm (22.4 in) (25 December 2001). The coldest recorded year was 1893 with an average January temperature of −10.4 °C (13 °F) and an annual temperature of 8.2 °C (46.8 °F). Summers are quite warm and sunny. In summer, the city generally remains slightly cooler than other parts of Bulgaria, due to its higher altitude. However, the city is also subject to heat waves with high temperatures reaching or exceeding 35 °C (95 °F) on the hottest days, particularly in July and August. The highest recorded temperature is 40.2 °C (104 °F) (5 July 2000). The hottest recorded month was July 2012 with an average temperature of 24.8 °C (77 °F). The warmest year on record was 2024 with an annual temperature of 12.5 °C (55 °F). Springs and autumns in Sofia are usually short with variable and dynamic weather. The city receives an average precipitation of 625.7 mm (24.63 in) a year, reaching its peak in late spring and early summer when thunderstorms are common. The driest recorded year was 2000 with a total precipitation of 304.6 mm (11.99 in), while the wettest year on record was 2014 with a total precipitation of 1,066.6 mm (41.99 in).
Demographics & Culture
According to 2018 data, the city has a population of 1,400,384 and the whole Sofia Capital Municipality of 1,500,120. The first census carried out in February 1878 by the Russian Army recorded a population of 11,694 inhabitants including 6,560 Bulgarians, 3,538 Jews, 839 Turks, and 737 Romani. The ratio of women per 1,000 men was 1,102. The birth rate per 1000 people was 12.3 per mile and steadily increasing in the last 5 years, the death rate reaching 12.1 per mile and decreasing. The natural growth rate during 2009 was 0.2 per mile, the first positive growth rate in nearly 20 years. The considerable immigration to the capital from poorer regions of the country, as well as urbanisation, are among the other reasons for the increase in Sofia's population. The infant mortality rate was 5.6 per 1,000, down from 18.9 in 1980. According to the 2011 census, people aged 20–24 years are the most numerous group, numbering 133,170 individuals and accounting for 11% of the total 1,202,761 people. The median age is 38 though. According to the census, 1,056,738 citizens (87.9%) are recorded as ethnic Bulgarians, 17,550 (1.5%) as Romani, 6,149 (0.5%) as Turks, 9,569 (0.8%) belonged to other ethnic groups, 6,993 (0.6%) do not self-identify and 105,762 (8.8%) remained with undeclared affiliation.

Of the population aged 15–64 – 265,248 people within the municipality (28.5%) are not economically active, the unemployed being another group of 55,553 people (6%), a large share of whom have completed higher education. The largest group are occupied in trading, followed by those in the manufacturing industry. Within the municipality, three-quarters, or 965,328 people are recorded as having access to television at home and 836,435 (64.8%) as having internet. Out of 464,865 homes – 432,847 have connection to the communal sanitary sewer, while 2,732 do not have any. Of these 864 do not have any water supply and 688 have other than communal.

The families that consist of two people are 46.8%, another 34.2% of the families are made up by three people, whereas most of the households (36.5%) consist of only one person. Sofia was declared the national capital in 1879. One year later, in 1880, it was the fifth-largest city in the country after Plovdiv, Varna, Ruse and Shumen. Plovdiv remained the most populous Bulgarian town until 1892 when Sofia took the lead. The city is the hot spot of internal migration, the capital population is increasing and is around 17% of the national, thus a small number of people with local roots remain today, they dominate the surrounding rural suburbs and are called Shopi. Shopi speak the Western Bulgarian dialects.
Sofia concentrates the majority of Bulgaria's leading performing arts troupes. Theatre is by far the most popular form of performing art, and theatrical venues are among the most visited, second only to cinemas. There were 3,162 theatric performances with 570,568 people attending in 2014. The Ivan Vazov National Theatre, which performs mainly classical plays and is situated in the very centre of the city, is the most prominent theatre. The National Opera and Ballet of Bulgaria is a combined opera and ballet collective established in 1891. Regular performances began in 1909. Some of Bulgaria's most famous operatic singers, such as Nicolai Ghiaurov and Ghena Dimitrova, made their first appearances on the stage of the National Opera and Ballet. Cinema is the most popular form of entertainment: there were more than 141,000 film shows with a total attendance exceeding 2,700,000 in 2014. Over the past two decades, numerous independent cinemas have closed and most shows are in shopping centre multiplexes. Odeon (not part of the Odeon Cinemas chain) shows exclusively European and independent American films, as well as 20th century classics. The Boyana Film studios was at the centre of a once-thriving domestic film industry, which declined significantly after 1990. Nu Image acquired the studios to upgrade them into Nu Boyana Film Studios, used to shoot scenes for a number of action movies like The Expendables 2, Rambo: Last Blood and London Has Fallen. Bulgaria's largest art museums are located in the central areas of the city. Since 2015, the National Art Gallery, located in the former royal palace, the National Gallery for Foreign Art and the Museum of Contemporary Art – Sofia Arsenal were merged to form the National Gallery. Its largest branch is Kvadrat 500, located on the NFGA premises, where some 2,000 works are on display in twenty eight exhibition halls. The collections encompass diverse cultural items, from Ashanti Empire sculptures and Buddhist art to Dutch Golden Age painting, works by Albrecht Dürer, Jean-Baptiste Greuze and Auguste Rodin. The crypt of the Alexander Nevsky cathedral is another branch of the National Gallery. It holds a collection of Eastern Orthodox icons from the 9th to the 19th century. The National History Museum, located in Boyana, it has a vast collection of more than 650,000 historical items dating from Prehistory to the modern era, although only 10,000 of them are permanently displayed due to the lack of space. Smaller collections of historical items are displayed in the National Archaeological Museum, a former mosque located between the edifices of the National Bank and the Presidency. Two natural sciences museums—the Natural History Museum and Earth and Man—display minerals, animal species (alive and taxidermic) and rare materials. The Ethnographic Museum and the Museum of Military History hold large collections of Bulgarian folk costumes and armaments, respectively. The Polytechnical Museum has more than 1,000 technological items on display. The SS. Cyril and Methodius National Library, the foremost information repository in the country, holds some 1,800,000 books and more than 7,000,000 documents, manuscripts, maps and other items.
Economy & Government
Sofia is ranked as Beta- global city by the Globalization and World Cities Research Network. It is the economic hub of Bulgaria and home to most major Bulgarian and international companies operating in the country, as well as the Bulgarian National Bank and the Bulgarian Stock Exchange. The city is ranked 62nd among financial centres worldwide. In 2015, Sofia was ranked 30th out of 300 global cities in terms of combined growth in employment and real gross domestic product per capita, the highest one amongst cities in Southeast Europe. The real GDP per capita growth at the time was 2.5% and the employment went up by 3.4% to 962,400. In 2015, Forbes listed Sofia as one of the top 10 places in the world to launch a startup business, because of the low corporate tax (10%), the fast internet connection speeds available – one of the fastest in the world, and the presence of several investment funds, including Eleven Startup Accelerator, LAUNCHub and Neveq. The city's GDP per capita stood at €29,600 ($33,760) in 2015, one of the highest in Southeast Europe and well above other cities in the country. The total nominal GDP in 2018 was 38.5 billion leva ($22.4 billion), or 33,437 leva ($19,454) per capita, and average monthly wages in March 2020 were $1,071, the highest nationally. Services dominate the economy, accounting for 88.6% of the gross value added, followed by industry 11.3% and agriculture 0.1%. Historically, after World War II and the era of industrialisation under socialism, the city and its surrounding areas expanded rapidly and became the most heavily industrialised region of the country, with numerous factories producing steel, pig iron, machinery, industrial equipment, electronics, trams, chemicals, textiles, and food. The influx of workers from other parts of the country became so intense that a restriction policy was imposed, and residing in the capital was only possible after obtaining Sofianite citizenship. However, after the political changes in 1989, this kind of citizenship was removed. The most dynamic sectors include Information technology and manufacturing. Sofia is a regional IT hub, ranking second among the Top 10 fastest growing tech centers in Europe in terms of annual growth of active members. The sector employs about 50,000 professionals, 30% of them involved in programming, and contributes for 14% of the city's exports. The IT sector is highly diverse and includes both multinational corporations, local companies and startups. Multinationals with major research, development, innovation and engineering centers in Sofia include the second largest global IT center of Coca-Cola, Ubisoft, Hewlett-Packard, VMware, Robert Bosch GmbH, Financial Times, Experian, etc. Several office and tech clusters have been established across the city, including Business Park Sofia, Sofia Tech Park, Capital Fort and others. Manufacturing has registered a strong recovery since 2012, increasing the exports three-fold and the employment by 52% accounting for over 70,000 jobs. Supported by the city's R&D expertise, Sofia is shifting to high value-added manufacturing including electrical equipment, precision mechanics, pharmaceuticals. There are 16 industrial and logistics parks in Sofia, some sprawling to towns in neighbouring Sofia Province, such as Bozhurishte, Kostinbrod and Elin Pelin. Manufacturing companies include Woodward, Inc., producing airframe and industrial turbomachinery systems, Festo, producing microsensors, Visteon, development and engineering of instrument clusters, LCD screens and domain controllers, Melexis, producing micro-electronic semiconductor solutions in the automotive sector, Sopharma, producing pharmaceuticals, the largest Lufthansa Technik maintenance facilities outside Germany, etc.
