Persepolis (Old Persian Pârsa, modern Takht-e Jamshid): Greek name of one of the capitals of the ancient Achaemenid Empire, founded by king Darius the Great (r.522-486 BCE). There were several satellite sites, Naqš-e Rustam and Takht-e Rustam.
The so-called Garrison Quarters are east of the palaces of Persepolis. Their function is unknown, and there is no certainty about the date of their construction. The name is just conventional. However, they were certainly constructed with or after the Hall of Hundred Columns, because they have the same dimensions. This means that these buildings were built by king Artaxerxes I Makrocheir (r.465-424) or one of his successors.
