Pasargadae was the capital of the Achaemenid Empire under Cyrus the Great who had issued its construction (559–530 BC); it was also the location of his tomb. It was a city in ancient Persia, located near the city of Shiraz (in Pasargad County), and is today an archaeological site and one of Iran's UNESCO World Heritage Sites. Cyrus the Great began building the capital in 546 BC or later; it was unfinished when he died in battle, in 530 or 529 BC. The remains of the tomb of Cyrus' son and successor Cambyses II have been found in Pasargadae, near the fortress of Toll-e Takht, and identified in 2006. Pasargadae remained the capital of the Achaemenid empire until Cambyses II moved it to Susa; later, Darius founded another in Persepolis.
