Naqsh-e Rustam is one of the most spectacular and awe-inspiring ancient sites of the Achaemenid Empire, consisting of the colossal tombs of Persian kings dating back to the first millennium BC. It stands as a lasting memory of a once powerful empire that ruled over a significant portion of the ancient world.
Naqsh-e Rustam (meaning Throne of Rustam) is located approximately 5 km (3 miles) to the northwest of Persepolis, the capital of the former Achaemenid (Persian) Empire in present day in Iran. Engraved on the façade of a mountain range considered sacred in the Elamite periods are the rock-cut tombs of Achaemenid rulers and their families dating to the 4th and 5th centuries BC, as well as richly decorated reliefs carved by the Sasanians in the 3rd century AD. In addition to being a royal necropolis, Naqsh-e Rustam became a major ceremonial center for the Sasanians until the 7th century AD.
