Adjacent to the Throne Hall is the Treasury, part of which served as an armory and especially as a royal storehouse of the Achaemenian kings. The tremendous wealth stored here came from the booty of conquered nations and from the annual tribute sent by the peoples of the empire to the king on the occasion of the New Year’s feast. Before the Throne Hall was finished, the most spacious room of the Treasury was used as a Court of Reception. Two large stone reliefs were discovered here that attested to its function. These depict Darius I, seated on his throne, being approached by a high dignitary whose hand is raised to his mouth in a gesture of respectful greeting. Behind the king stands Crown Prince Xerxes, followed by court officials.
