Altar of the Twelve Gods

The Altar of the Twelve Gods (also called the Sanctuary of the Twelve Gods), was an important altar and sanctuary at Athens, located in the northwest corner of the Classical Agora. The Altar was set up by Pisistratus the Younger, (the grandson of the tyrant Pisistratus) during his archonship, in 522/1 BC. It marked the central point from which distances from Athens were measured and was a place of supplication and refuge.
