Town Hall of Ephesus, (Prytaneion). In the holy sector of the city, stood the Altar of Hestia, where the holy eternal flame of the city burned. The fact that both of the statues of Artemis Ephesia were found in the ruins of the Town Hall would indicate that the building also had a religious function.
Only the square altar of the eternal flame of the town hall remains from the Hellenistic Period. The rest of the structure was re-built during the Roman Period. The buildings adjoining the Town Hall served as service structures.
