The Serdika neighborhood is the archaeological heart of Sofia, a place where millennia of history literally emerge from the ground.
Walking through its streets means taking a journey through time, from the remains of the 4th-century Roman city to the buildings of real socialism, passing by early Christian churches and Ottoman mosques. For those planning vacation in Sofia, a walking itinerary in the Serdika neighborhood is the best way to understand the historical layering of the Bulgarian capital, without having to cover long distances. This guide proposes a circular route of about 2 kilometers, which touches the main archaeological sites and monuments in the area.
Starting Point: Serdika Metro Station
The itinerary begins at the Serdika metro station, accessible via lines M1 and M2. Even here, before stepping outside, one can admire one of the most striking urban archaeological finds in Europe. During the excavations for the construction of the metro, the ruins of a paved Roman road emerged, with columns, capitals, and remains of public buildings. All of this has been integrated into the station's underpass, protected by glass and illuminated. During the vacation in Sofia, this metro stop is in itself a small attraction, a taste of what will be found above ground.
The Remains of the Roman City of Serdica
Serdica was the Roman name for Sofia, a thriving city in the 4th century AD, when it became an imperial residence under Constantine the Great. The currently visible ruins belong to this period: baths, streets, a forum, and a civil basilica. The archaeological area extends for about one and a half hectares, with excavations still ongoing. During the holidays in Sofia, walking among these ruins is an immersion into the daily life of antiquity, when the city was an important hub on the military road connecting Europe to Asia.
First Stop: The Rotunda of St. George
Exiting the Serdika station, you cross the square and reach the Rotunda of St. George, hidden among government buildings and hotels. This small red brick structure is the oldest preserved building in Sofia, dating back to the 4th century AD. Originally built as a thermal or civil building, it was transformed into a Christian church already in late antiquity. The interior is essential, with medieval frescoes and surprising acoustics. The rotunda is open to the public with variable hours. During the holidays in Sofia, visiting it early in the morning, when light enters through the windows, provides an intimate and cozy atmosphere.
The History of the Rotunda
The Rotunda of St. George has gone through all the epochs of Bulgarian history: Roman, Byzantine, Ottoman, and modern. During the Ottoman rule, it was used as a mosque, then as a storage facility, and finally restored in the 20th century. The interior frescoes, depicting saints and biblical scenes, date back to the 12th-13th century and are among the few surviving examples of early Bulgarian art. During the holidays in Sofia, stopping here for a few minutes of silence allows you to feel the weight of the centuries.
Second Stop: The Banya Bashi Mosque and the Roman Baths
A few steps separate the Rotunda from the Banya Bashi Mosque, one of the few active mosques in Sofia. Built at the end of the 16th century, it stands out for its large dome and minaret. The peculiarity is that it is built over natural hot springs: from the surrounding sidewalk, you can see steam rising from the grates, and the hot water is still used for the nearby baths. Next to the mosque are the remains of the Roman baths of Serdica, partially visible and under excavation. During the holidays in Sofia, observing this combination of Ottoman architecture and Roman remains is fascinating.
The Central Market and the Hot Springs
Continuing on, you arrive at the Central Market (Tsentralni Hali), described in the previous cluster article. But before entering, it is worth noting the hot springs that have been flowing since Roman times and today supply the city's public baths. The water, rich in minerals, has a constant temperature of about 40°C. During the holidays in Sofia, stopping to watch the steam rising from the sidewalk is a small spectacle of nature that blends with history.
Third Stop: The Archaeological Area of Serdica (Open Excavations)
Exiting the market and continuing east, you encounter the large archaeological area of Serdica, an open-air excavation site that extends below street level. Here, the foundations of Roman public buildings, paved streets, mosaics, and heating systems (hypocausts) are visible. The site is crossed by pedestrian walkways that allow you to walk above the ruins, observing them up close. During the holidays in Sofia, this is one of the most picturesque points of the route, as it shows the Roman city in its entirety.
The Mosaics of Serdica
Among the most spectacular finds in the archaeological area are the floor mosaics from the Roman and early Christian periods. Geometric patterns, stylized animals, and mythological scenes decorate the floors of the baths and the domus. Some mosaics have been restored and are protected by canopies. During the holidays in Sofia, it is worth pausing to observe the details of these ancient artifacts, which testify to the high artistic level achieved by the city in imperial times.
Fourth Stop: The Church of Saint Sofia
Exiting the archaeological area, one ascends towards the square where the basilica of Saint Sofia stands, which gives the city its name. This 6th-century early Christian church is one of the oldest religious buildings in the Balkans still in use. The interior is bare, almost austere, with granite columns and Corinthian capitals. Beneath the church is an archaeological area with tombs and sarcophagi from the Roman and medieval periods. During the holidays in Sofia, visiting Saint Sofia is a dive into the Christian origins of the city.
The Crypt and the Tombs
The crypt of the Church of Saint Sofia is open to visitors and houses numerous tombs, some with frescoes and funerary inscriptions. The most famous is that of Bishop Protogen, dating back to the 5th century. The underground atmosphere is evocative and silent. During the holidays in Sofia, descending into the crypt is an experience that completes the visit to the church and offers a glimpse into early Christianity.
Fifth Stop: The Alexander Nevsky Cathedral
A few steps from Saint Sofia, the Alexander Nevsky Cathedral rises majestically, already described in article cluster no. 4. This stop ideally concludes the itinerary in the Serdika neighborhood, although architecturally the cathedral belongs to a later era (early twentieth century). The square in front offers a panoramic view of the city and Mount Vitosha. During the holidays in Sofia, sitting on the steps of the cathedral at sunset is a perfect way to mentally retrace the stages of the journey.
Variant: The Presidential Palace and the Statue of Sofia
For those who wish to extend the itinerary, one can continue towards the Presidential Palace (the former royal palace) and the statue of Sofia, a large bronze sculpture that stands at the center of an intersection. The statue, erected in 2000, depicts the goddess Sofia with a crown, scepter, and an owl (symbol of wisdom). The presidential palace is a neoclassical building that houses the offices of the Bulgarian president and the honor guard, whose change occurs ceremonially at certain times. During the holidays in Sofia, this variant adds an institutional and contemporary touch to the historical route.

The Significance of Serdika in Bulgarian History
Serdika was not just a Roman city. It was the place where Constantine the Great stayed several times, where important edicts were issued, and where ecclesiastical councils were held in the 4th century. The city was then destroyed and rebuilt several times, but each era has left its mark. Walking in the Serdika neighborhood during the holidays in Sofia means reading the history of Bulgaria in a single urban space, where Roman, Byzantine, Ottoman, and modern coexist.
