The Stoa of Zeus (Eleutherios) at Athens, was a two-aisled stoa located in the northwest corner of the Ancient Agora of Athens. It was built c. 425 BC–410 BC for religious purposes in dedication to Zeus by the Eleutherios (Freedom): a cult founded after the Persian War. It is different from others in that it was a stoa rather than a temple (the common building used for religious purposes). Scholars believe the building also served other civic purposes due to its central location. Researchers think the structure may have been built by Mnesikles, the architect who built the Propylaia.
