The stadium was built in the beginning of the 2nd century AD during the reign of the emperor
Hadrian (). Approximately m long and 50 m wide, it could seat up to 30000 spectators. The length of the track is one
stadion – 625
Roman feet or 600
Greek feet, or approximately . The spectators' seats are tiered in 14 rows, crossed by stepped aisles down to the track. The seats are made of solid marble blocks (40 cm high and 75 cm wide) and the front parts are decorated with stylized lion paws. The front part of the lowest row is revetted with massive marble 1.80-metre plates (
orthostats) on solid marble blocks. The seats from the highest row had backrests. Like the other imperial buildings for spectacular events, the stadium had its
seats of honour () preserved by inscriptions in the marble blocks. Seats with Greek inscriptions were found, proving the existence of special seats for members of higher public position. 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. The northern curved part of the stadium is
in situ in Dzhumaya Square. Also a covered vaulted passage under the tiered rows of seats (
cavea) links the track with the outside Roman road next to the city walls. In the 4th century AD this area was crossed by an ancient
Roman aqueduct, the arch support of which remains. == Games ==
