The Ka&#x27;ba-ye Zartosht (&quot;Cube of Zoroaster&quot;) is a 5th century BC Achaemenid-era tower-like construction at Naqsh-e Rustam, northwest of Persepolis, Iran. The name probably dates to the 14th c., when many pre-Islamic sites were identified with figures and events of the Qur&#x27;ān or the Shāhnāme. The structure is not actually a Zoroastrian shrine. The structure, which is a copy of a sister building at Pasargadae, was built either by Darius I when he moved to Persepolis, by Artaxerxes II or III.
