The Ancient Theatre of Delphi, located within the Sanctuary of Apollo, hosted the vocal and instrumental music competitions of the Pythian Games as well as other religious festivals. The first stone theatre was built in the 4th century BC, while its present form, featuring the stone-paved orchestra, stone seating and stage, was created during the early Roman period through the patronage of Eumenes II of Pergamon. The theatre could accommodate around 5,000 spectators, with its seating area divided into two tiers and a horseshoe-shaped orchestra. Today, the orchestra, the inscriptions on the passage walls and the foundations of the stage are preserved, while the façade of the proscenium was decorated in the 1st century AD with a frieze depicting the Labours of Heracles.
