Ancient cultural and communication complex “Serdica” combines areas with various purposes, divided into two zones. The “Largo” zone, situated underneath Nezavisimost Square, integrates the unearthed archaeological remains into a site for cultural events. The remains of one of the two main streets of the Roman town, the decumanus maximus, which connects the eastern and the western gate of the city, can be seen here. A large residential building, covering an entire insula (urban block), can be seen south of it. The building also had small shops, from which travelers and the town’s inhabitants could purchase food and various goods. A lapidarium is located close to the building.
