A tour to Persepolis should include a visit to the nearby rock tombs and reliefs of Naqsh-e Rostam and Naqsh-e Rajab. The former consists of four massive tombs built into the face of a cliff, an appropriately ostentatious final resting place for four Achaemenid kings. Below you will see some stone reliefs depicting various Sassanian imperial triumphs, such as the Roman Emperor Valyerian kneeling before Shapur I. Four more Sassanian reliefs can be found at the less well-tended Naqsh-e Rajab, only five minutes away.
