Largo Archaeological Complex

About

The Largo Archaeological Complex in Sofia is a remarkable fusion of ancient history and modern urban life, located beneath Independence Square in the city’s heart. This open-air and subterranean museum reveals the remains of ancient Serdica, the Roman predecessor of Sofia. Visitors can walk along the decumanus maximus—the main Roman street—flanked by remnants of shops, homes, and public buildings dating from the 4th to 6th centuries. Highlights include early Christian basilicas, thermae, and the intricately preserved Felix mosaic. The complex is divided into two zones: one beneath the square, used for exhibitions and cultural events, and another under Knyaginya Maria Luiza Boulevard, showcasing elite Roman residences with private baths and heating systems. Transparent domes and walkways allow for year-round access and visibility. With free daily entry and a central location, the Largo offers a vivid, accessible journey into Sofia’s Roman past, seamlessly integrated into the city’s contemporary rhythm.

Location

The Largo Archaeological Complex, also known as the Ancient Serdica Archaeological Complex, is located in the very center of Sofia, beneath and around Independence Square (Nezavisimost Square). This area is framed by some of Sofia’s most important government buildings, including the Council of Ministers, the Presidency, and the former Communist Party headquarters, now the National Assembly building. The complex is easily accessible and sits above the Serdika II metro station, making it a convenient stop for tourists exploring the city. For visitors, the Largo is a unique site where you can walk among the exposed ruins of the ancient Roman city of Serdica, including streets, residential buildings, early Christian basilicas, and public baths, all integrated into a modern urban setting under glass domes and open-air sections. Nearby, you’ll find the Central Department Store (TSUM), the Banya Bashi Mosque, the Sofia Synagogue, the Central Market Hall, and the St. Nedelya Church, all within a short walking distance. The area is also close to the main pedestrian shopping street, Vitosha Boulevard, and the National Archaeological Museum. This central location makes the Largo Archaeological Complex a must-see for those interested in Sofia’s ancient history and its vibrant city life today.
