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 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.

The initial project name of the Metro Station was Sveta Nedelya Square, but this was changed by the city council shortly before the opening of M2 line.
