Pasargadae is the deserted capital of the Achaemenid Persians, founded ca 550 BCE by Cyrus the Great (reg. 559-530 BCE).
Principal structures include the tomb of Cyrus, the Zendan-i Suleyman, the Tall-i Takht, an open-air enclosed prayer area, a palace complex with a gatehouse (Gate R, also called Palace R or Palace with the Relief), Palace P, from Herzfeld's "Palast mit der Pfeiler," or Palace with the (gateway) Pillar, and Palace S (Herzfeld's "Palast mit der Saule," or Palace with the Column). These structures, placed at a distance from one another, were once linked by a set of gardens. It is possible that Pasargadae represents the first appearance of the chahar bagh garden.
