A fragment of the substructure of the Eastern wall from the Northern extension of the Late Antique Serdica fortification was registered during rescue archaeological excavation in the area of the Lion Bridge square. Detailed investigations have identified three construction levels of the foundation of the structure - stones bound with solid white mortar, stones bound with yellow sandy mortar and a leveling layer of loose  mortar and single stones. The stratigraphy of the site consists of three chronological groups: Late Ottoman/Revival (17th-19th century), Medieval (11th-12th century) and Late Antiquity (4th-5th century). Artifacts and numismatic materials date the construction of the fortress wall between the last decades of the reign of Emperor Constantine I and the end of 4th/ beginning of the 5th  century AD.
