Archaeological evidence shows that the earliest remains of Persepolis date back to 515 BC. André Godard, the French archaeologist who excavated Persepolis in the early 1930s, believed that it was Cyrus the Great (Kūrosh) who chose the site of Persepolis, but that it was Darius I (Daryush) who built the terrace and the great palaces.

Darius ordered the construction of the Apadana Palace and the Council Hall (the Tripylon or three-gated hall), the main imperial Treasury and its surroundings. These were completed during the reign of his son, King Xerxes the Great . Further construction of the buildings on the terrace continued until the downfall of the Achaemenid dynasty.
