The sanctuaries of Pandion and Zeus Polieus, Zeus of the city, stood at the eastern end of the Acropolis.
In the history of Athens there were two heroes named Pandion. One was the son of Erichthonios, the other the grandfather of Theseus, favourite hero of the Athenians. It is not known for which of these two heroes the sanctuary was built.
The sanctuary of Zeus Polieus may have included a barn for keeping the sacred oxen that were sacrificed to the god.
