The magnificent palace complex at Persepolis was founded by Darius the Great around 518 B.C., although more than a century passed before it was finally completed. Conceived to be the seat of government for the Achaemenian kings and a center for receptions and ceremonial festivities, the wealth of the Persian empire was evident in all aspects of its construction.
