The Ancient Agora of Athens is a flat area defined by the Sacred Rock of the Acropolis and the hill of Areopagus in the south and the hill of Kolonos Agoraios in the west. It is traversed by one of the most important ancient roads, the Panathenaic Way, which led to the Acropolis from the main gate of the city, the Dipylon Gate. This road served as the processional way for the great parade of the Panathenaic festival, which was held to honour the city patron goddess Athena.

On top of Agoraios Kolonos hill, stands the temple of Hephaestus, broadly known as Thisio. It is one of the best preserved ancient temples, partly because it was transformed into a Christian church. According to the traveller and geographer Pausanias (1, 14, 5-6), two deities were jointly worshipped in the temple: god Hephaestus, protector of all metallurgists, and goddess Athena Ergani, protecting all potters and the cottage industries. The identification of this temple as ?Hephaesteion? (location of worship of the god Hephaestus) was ascertained by the excavations and investigations that brought to light metallurgy workshops on the wider area of the hill, thus outshining earlier opinions presuming that Theseus, Hercules or Aris (Mars) were the deities worshipped there. The temple was probably erected between 460 and 420 BC by a yet unknown architect, to whom, however, are attributed other temples of similar structure in the Attica region

Le Musée de l'Agora antique est installé dans la Stoa d'Attale reconstruite, érigée au IIe siècle av. J.-C., offerte à Athènes par le roi de Pergame, Attale II. L'exposition de la galerie du musée présente des découvertes archéologiques issues des fouilles systématiques menées dans la région par l'École américaine d'études classiques et datant du Néolithique aux périodes post-byzantine et ottomane.
