Just a few kilometers north of Persepolis, the monumental tombs of Darius II, Artaxerxes I and Darius I were hewn into a rock cliff, called Naqsh-e-Rostam.
The tomb facades are of huge dimensions (75 feet high and 61 feet wide) and embellished with sculpted figures. In the middle of the cross-shape design a door leads to the sepulchre interior vaults.
Many of the later kings displayed their triumphs there, through pictures carved in the rock at the side of the tombs.
In front of the rock where royal tombs were built stand also an ancient fire temple, a simple tower with a staircase leading to a room inside, where priests kept the flame burning.
