Naqsh-e Rustam is an ancient “graveyard” about 12 km from Persepolis. PSA: we arrived here a couple of minutes after 6 PM and unfortunately the gates were closed so I had to view the tombs from behind the gates and managed to snap some quick photos.
The oldest site at Naqsh-e Rustam dates back to 1000 BC. At the site, there are four Achaemenid tombs that belonged to Achaemenid kings. The tombs are carved out of the rock in the mountainside at a considerable height above ground. The tombs are known as the “Persian crosses” and the entrance to each tomb is at the center of each cross. In the chamber within the tomb, the king was buried in a sarcophagus.
One of the tombs is explicitly identified as belonging to Darius I the Great. The other three are believed to be those of Xerxes I, Artaxerxes I, and Darius II. The tombs were looted following the conquest of the Achaemenid Empire by Alexander the Great.
