Persepolis was the ceremonial capital of the Achaemenid Empire (ca. 550–330 BC). 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. UNESCO declared the citadel of Persepolis a World Heritage Site in 1979.

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 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 (Khashayar). Further construction of the buildings on the terrace continued until the downfall of the Achaemenid dynasty.


Gate of All Nations
The Gate of all Nations, referring to subjects of the empire, consisted of a grand hall that was a square of approximately 25 metres (82 ft) in length, with four columns and its entrance on the Western Wall. There were two more doors, one to the south which opened to the Apadana yard and the other opened onto a long road to the east. Pivoting devices found on the inner corners of all the doors indicate that they were two-leafed doors, probably made of wood and covered with sheets of ornate metal.
A pair of Lamassus, bulls with the heads of bearded men, stand by the western threshold. Another pair, with wings and a Persian head (Gopät-Shäh), stands by the eastern entrance, to reflect the Empire’s power.
Xerxes's name was written in three languages and carved on the entrances, informing everyone that he ordered it to be built.


Tombs of Kings
It is commonly accepted that Cyrus the Great was buried at Pasargadae. If it is true that the body of Cambyses II was brought home "to the Persians", his burying-place must be somewhere beside that of his father. Ctesias assumes that it was the custom for a king to prepare his own tomb during his lifetime. Hence the kings buried at Naghsh-e Rustam are probably Darius I, Xerxes I, Artaxerxes I and Darius II. Xerxes II, who reigned for a very short time, could scarcely have obtained so splendid a monument, and still less could the usurper Sogdianus (Secydianus). The two completed graves behind Takhti Jamshid would then belong to Artaxerxes II and Artaxerxes III.

The unfinished one is perhaps that of Arses of Persia, who reigned at the longest two years, or, if not his, then that of Darius III (Codomannus), who is one of those whose bodies are said to have been brought "to the Persians."


Another small group of ruins in the same style is found at the village of Hajjiäbäd, on the Pulwar, a good hour's walk above Takhti Jamshid. These formed a single building, which was still intact 900 years ago, and was used as the mosque of the then-existing city of Istakhr.

Cyrus the Great was buried in Pasargadae, which is mentioned by Ctesias as his own city. Since, to judge from the inscriptions, the buildings of Persepolis commenced with Darius I, it was probably under this king, with whom the sceptre passed to a new branch of the royal house, that Persepolis became the capital of Persia proper. As the residence of the rulers of the empire, however, a remote place in a difficult alpine region was far from convenient. The country's true capitals were Susa, Babylon and Ecbatana. This accounts for the fact that the Greeks were not acquainted with the city until Alexander the Great took and plundered it.

At that time Alexander burned "the palaces" or "the palace," universally believed now to be the ruins at Takhti Jamshid. From Stolze's investigations it appears that at least one of these, the castle built by Xerxes, bears evident traces of having been destroyed by fire. The locality described by Diodorus after Cleitarchus corresponds in important particulars with Takhti Jamshid, for example, in being supported by the mountain on the east.
