To the southeast lay the Treasury, a labyrinth of storerooms where unimaginable wealth accumulated. Greek historians claimed that Alexander required thousands of pack animals to haul away its contents of gold and silver. Within were also found reliefs originally adorning the Apadana, later relocated—perhaps for political reasons. These images of royal audiences, carefully curated and concealed, suggest the treasury was not only economic but ideological, safeguarding symbols of legitimacy.
