Persepolis

Persepolis  was the ceremonial capital of the Achaemenid Empire (ca. 550-330 BCE). Persepolis is situated 70 km northeast of the modern city of Shiraz in the Fars Province of modern Iran.  The earliest remains of Persepolis date from around 515 BCE. To the ancient Persians, the city was known as Pārsa, which means "The City of Persians". Persepolis is a transliteration of the Greek (Persēs polis: "Persian city").

Archaeological evidence shows that the earliest remains of Persepolis date from around 515 BC. André Godard, the French archaeologist who excavated Persepolis in the early 1930s, believed that Cyrus the Great (Kūrosh) who chose the site of Persepolis, but that it was Darius the Great 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.
