More remote along the Sacred Way we see the establishments of an old sanctuary before the Erechtheion. Because of its length of 100 Attic feet, this building was wrongly accepted for quite a long time to be the Hecatompedon, until distinguished as the Old Temple of Athena Polias (Athena of the City). This is the most old building revealed on the Acropolis; it was initially a basic haven dating from the remotest times. The unobtrusive Doric sanctuary of limestone was reestablished in the 6th century BC by Peisistratus, who adorned it by including a corridor and pediments delineating a Battle of the Giants, while its opisthodomos served as the Athenian Treasury.
In this load of stones, encased by a railing, we can recognize two bases in poros for the backing of wooden columns having a place with the Mycenaean megaron (royal residence) of the primary King of Athens. This was the focal point of the general population life of the fortification and reached out similarly as the north mass of the Erechtheion. A flight of rock-cut strides worked in Pelasgic times associated the megaron and the Acropolis with the lower city. Later, in recorded times, on these Mycenaean remnants was raised the aforementioned Temple of Athena Polias, a rectangle of 32.80 m. long, that is 100 feet, whence its name of "Hecatompedon" (sanctuary of a hundred feet). This sanctuary was remade after it was destructed amid the persian attack yet it creates the impression that after the finish of the Erechtheion it got to be pointless and an encumbrance, and was at long last pulverized in 406 BC.
Inverse the remains of the Old Temple of Athena Polias and near the seventh segment of the Parthenon, there is an engraving which understands: This spot was blessed, in the wake of being shown by a prophet, to the Fruitful Earth. Precisely on this spot was a statue of Earth importuning Zeus to send downpour. Adjacent is a roundabout base, which some time ago bore the statues of Conon and his child Timotheus and more remote along is the base of a statue devoted to Hermolycos, child of Deitrephes.
