The Serdica Archaeological Complex is an open-air and underground display of the Roman city of Serdica, located at Largo around the Serdika metro station in central Sofia, Bulgaria. Serdica was an important Roman city in the province of Thrace and later Dacia, and the excavations uncovered paved streets, residential buildings, sections of the city walls and the East Gate, which stood on the route between Western Europe and Constantinople.

The Serdica Archaeological Complex is an open-air and underground display of the Roman city of Serdica, located at Largo around the Serdika metro station in central Sofia, Bulgaria. Serdica was an important Roman city in the province of Thrace and later Dacia, and the excavations uncovered paved streets, residential buildings, sections of the city walls and the East Gate, which stood on the route between Western Europe and Constantinople. The site is unusual because the ruins were integrated into the modern city during the building of the metro, so visitors walk through the station concourse and see sections of the Roman street, drainage channels and walls beside the ticket machines. Outside, a glassed-over area near the Largo ensemble shows more of the ancient road and fortress remains. Information panels in Bulgarian and English explain the layers of the city, from the Thracian Serdi tribe through Roman, Byzantine and medieval periods. The underground galleries are accessible during metro operating hours, roughly from 05:00 to 24:00, and the outdoor ruins can be seen at any time. A visit takes 30 to 45 minutes and combines easily with Sveta Nedelya Church, the nearby Rotunda of St George and Banya Bashi Mosque. Late afternoon is attractive because the Largo ensemble, a Stalinist-era government complex, is lit and the site is in shade. Rainy days also suit it well because much of the route is covered. Crowds are heaviest at commuting hours when the metro concourse fills, so visitors who want to read the panels in peace do better mid-morning or mid-afternoon. Entry is free. The complex is also a good starting point for a walking route through the historic centre, since the Largo, the former Party House, the Presidency and the Rotunda are all within a few minutes on foot.
