The outside walls of the "cavea" are built from granite ashlars, labelled with letters at some places. The architectural marble elements of the entrance and the orthostats on the front row were tied to each other with lead-set iron cramps. The main southern entrance to the stadium is formed by masonry pillars decorated with marble pilasters and reliefs. On the pilasters there are busts of Hermes ("hermai") with prize vases decorated with palmettes placed above them, accompanied by the attributes of the god Heracles (the Roman Hercules) – his lion skin, club, and quiver. In front of the entrance a granite pavement was uncovered, consisting of hexagonal blocks – 0.70 by 0.70 m diagonally.
