Sanctuary of Pandion

The Sanctuary of Pandion is the name sometimes given to the remains of a building located in the south-east corner of the Acropolis of Athens. Its foundations were found during the excavations for the construction of the Old Acropolis Museum (1865-1874).

The 40m by 17m rectangular open-air building, dating to the later fifth-century, was divided into two nearly equal parts by a wall. It faced west-northwest and was entered through a projecting portico on the western side.

The name stems from the presumption that this was the location of the heroon ("hero shrine") of Pandion, the eponymous hero of the Attic tribe Pandionis (usually assumed to be one of the two legendary kings of Athens, Pandion I or Pandion II), which was known to be located somewhere on the Acropolis.
