The Trakart Cultural Center preserves and showcases a priceless piece of cultural heritage – Roman floor mosaics dating back to 2-3rd century AD. Located in the Archeological underpass, the exhibition is a piece of the EIRENE building from the late-antiquity. Only the southern part of the complex has been uncovered. The museum exhibits include the “Glass in Ancient Art”, “Proto-Thracian Portrait” and “Miniature Marble Portrait” permanent expositions.
