What was inside the Athenian Parthenon?
the tomb of goddes Athena
Although the Parthenon is architecturally a temple and is usually called so, it is not really one in the conventional sense of the word. It never hosted the cult of Athena Polias, patron of Athens. The Parthenon was actually used primarily as a treasury. For a time, it served as the treasury of the Delian League, which later became the Athenian Empire.
