Ancient Athens's largest building, the Panathenaic Stadium, has a capacity for 60,000 spectators. Constructed around 335 BC during the era of Herodes Atticus, the venue hosted the Panathenaic Games where runners competed in races around the track.
The 204-meter-long track was designed with four double herms, where runners would turn in the races.
Around AD 140, the stadium was updated with new marble seating by Herodes Atticus.
