Church of St. Nicholas, Sofia

The Church of Saint George (Bulgarian: Ротонда „Свети Георги“, romanized: Rotonda "Sveti Georgi") is a Late Antique red brick rotunda in Sofia, Bulgaria. Built in the early 4th century as Roman baths, it became a church inside the walls of Serdica, capital of ancient Dacia Mediterranea during the Roman Empire and Byzantine Empire. The Early Christian church is considered the oldest building in modern Sofia and belongs to the Bulgarian Orthodox Church. The building, a cylindrical domed structure built on a square base, is famous for the 12th-, 13th-, and 14th-century frescoes inside the central dome. Three layers of frescoes have been discovered, the earliest dating back to the 10th century. Magnificent frescoes of 22 prophets over 2 metres tall crown the dome. Painted over during the Ottoman period, when the building was used as a mosque, these frescoes were only uncovered and restored in the 20th century.

It occupies the building of the largest and oldest former Ottoman mosque in the city, originally known as Koca Mahmut Paşa Camii. The construction started in 1451 under grand vizier Veli Mahmud Pasha but due to his death in 1474 the mosque has been completed in 1494. The museum was established as a separate entity in 1893 as the National Museum directed by Czech Václav Dobruský with its headquarters in the former mosque that previously housed the National Library between 1880 and 1893. The museum was officially opened and inaugurated in 1905, as by then all archaeological exhibits previously kept all over the city were moved there, in the presence of Knyaz Ferdinand of Bulgaria and Minister of Enlightenment Ivan Shishmanov. Several additional halls and administrative buildings of the museum were constructed in the following years, which continues to use the historic stone building of the old mosque despite the often unfavourable conditions, notably the humidity in the summer. The museum has five exhibition halls: Central Hall, Prehistory, Middle Ages, Treasure, and a special temporary exhibition. It is managed by the Bulgarian Academy of Sciences.

The Largo (Bulgarian: Ларго, definite form Ларгото, Largoto) is an architectural ensemble of three Socialist Classicism edifices in central Sofia, the capital of Bulgaria, designed and built in the 1950s with the intention of becoming the city's new representative centre. Today it is regarded as one of the prime examples of Socialist Classicism architecture in Southeastern Europe, as well as one of the main landmarks of Sofia. The yellow-cobblestoned square around which the ensemble is centred is called Nezavisimost (Independence) Square. Independence Square is formed by the Knyaz Aleksandar Dondukov Boulevard and Tsar Osvoboditel Boulevard merging from the east to continue as Todor Aleksandrov Boulevard west of the Largo. The ensemble consists of the former Party House (former headquarters of the defunct Bulgarian Communist Party), now used as the seat of the National Assembly of Bulgaria, in the centre, and two side edifices: one today accommodating the TZUM department store and the Council of Ministers of Bulgaria and another that is today occupied by the President's Office, the Sofia Hotel Balkan and the Ministry of Education.

The Church of St Petka of the Saddlers (Bulgarian: Църква „Света Петка Самарджийска“) is a medieval Bulgarian Orthodox church in Sofia, the capital of Bulgaria. It is a small one-naved building partially dug into the ground located in the very centre of both the modern and the antique city, in the TZUM underpass. The church features a semi-cylindrical vault, a hemispherical apse, and a crypt discovered during excavations after the Second World War. The walls are 1 m thick and made from brick and stone. The church was first mentioned in the 16th century and was constructed at the place of a former Roman religious building. It is today a monument of culture known for its mural paintings from the 14th, 15th, 17th and 19th century depicting biblical scenes. The church is dedicated to St Petka, an 11th-century Bulgarian saint. The Church of Saint Petka acquired its present name due to it being a patron of the saddlers in the Middle Ages, who performed their rituals in the church. The adjective samardzhiyski ("of the saddlers") was derived from the Ottoman Turkish word semerci, meaning "saddlemaker". According to one theory, Bulgarian national hero Vasil Levski is buried in the church. Press reports from 1937 retelling the stories of those who carried out a reburial, which might have been for Levski and reports from the 1956 excavation speculating that bones found might have been those indicated by the 1937 press, led to the skeleton labeled "No. 95", being sent for professional examination. When Magdalina Stancheva museologist and head of the Archaeology Department at the Sofia Regional Historical Museum received the bones, she sent them to the laboratory run by Petîr Boev at the Archaeological Institute for examination. The bones were either destroyed by mice or lost. Nikolai Khaitov, a popular writer, accused Stancheva; archaeologists Georgi Dzhingov and Stamen Mikhailov; Krîstiu Miiatev, director of the Archaeological Institute; and Todor Pavlov, president of the National Academy of Bulgaria of participating in a conspiracy to prevent investigation into Levski's burial site and publicly accused Stancheva of mishandling the remains. Two commissions met over the controversy in the 1980s, and confirmed that there was no proof which could substantiate that the bones were Levski's, as the bones were missing.

Adorned with the symbols of power (crown), fame (wreath) and wisdom (owl), the crown is also a reference to the Goddess of Fate, Tyche, inspired by the old emblem of Sofia dating back to 1900.

Serdika Metro Station (Bulgarian: Метростанция „Сердика“) is an M1 and M4 lines station of Sofia Metro. It was put into operation on 31 October 2000. With the opening of Serdika II on 31 August 2012 the station became an interchange between the Red and Blue lines. However it is not a true interchange (such as platforms 3, 4, 5 and 6 of Canning Town station in London), but an interconnected station, in a similar manner to the Washington Metro's two Farragut stations.The station is named after the ancient city of Serdica, as it lies in the very centre of the hitherto unearthed ruins of that city. These are located about six meters (20 feet) below ground and, along with the opening of Serdika II station, a large section of the old city has been exposed and is in full view both around and inside the two stations. Serdika is one of only three metro stations in the world where the same line passes through the station twice in a pretzel configuration, the others being the Monument Metro station on the Tyne and Wear Metro in Newcastle upon Tyne, England, and Voorweg RandstadRail station on the Randstadrail in The Hague, Netherlands.

The City Garden (Bulgarian: Градска градина, Gradska gradina) is Sofia, the capital of Bulgaria's oldest and most central public garden, in existence since 1872. It is located between Tsar Osvoboditel Boulevard to the north, Knyaz Alexander Battenberg Street to the west and Joseph Vladimirovich Gourko Street to the south, in the historical centre of the city. Originally arranged in the last years of the Ottoman rule of Bulgaria, it was radically transformed immediately after the Liberation of Bulgaria in 1878 and the choice of Sofia as the capital the following year under the city architect Antonín Kolář on the initiative of the temporary governor Pyotr Alabin. The alley network was reorganized, new plants were added, as well as a low wooden fence, a coffeehouse and a kiosk for musicians. The garden was initially named the Alexander II Garden in honour of Russian tsar Alexander II, who initiated the Russo-Turkish War of 1877-78, which led to the Liberation of Bulgaria. Until the end of the 19th century the City Garden was repeatedly reorganized and further developed. Among the noted gardeners that worked on it were Karl Betz, Daniel Neff and Iliya Todorov, who shaped the garden's appearance that it would retain until the Second World War. The construction of the now-demolished Georgi Dimitrov Mausoleum soon after the beginning of Communist rule of Bulgaria after the war was followed by multiple fundamental reorganizations, such as in 1951 and 1959 by Sugarev and R. Robev, 1976 and 1978 by A. Agura. These led to the orientation of the garden not towards the former royal palace as previously, but towards the Ivan Vazov National Theatre. The new composition was often in conflict with the initial planning and the City Garden lost territory and key architectural elements in the period. Today the City Garden is not only a popular retreat for the residents of the capital, but also a favoured place for amateur chess players, who can be regularly seen in the small garden in front of the National Theatre. It was also the place where a group of around 300 people gathered on 27 August 1895 to climb Cherni vrah in Vitosha led by the writer Aleko Konstantinov on what is regarded as the birth date of tourism in Bulgaria.
