DVD. Cities of the World. 60 Minutes. Iran - formerly Persia - is the biggest country of the Middle East. Due to the fact that sky-high snowy mountains, extended deserts, verdant oases, turquoise cupola mosques and cultural and architectural relic sites of World Heritage are waiting for all visitors, it can be a very desirable destination even for tourists. In Tehran, the luxurious palaces of Persian shahs, the Museum of Archaeology and the Museum of Carpets and Rugs are the sights that "must" be seen. Yazd and Kerman is well-known for their mosques and bazaars, Naqsh-e Rustam is for its rock-hewn tombs, Rayen and Persepolis are for the remains of their palaces and castles from the time of the Persian Empire. The two most beautiful cities of Iran are the splendidly situated Shiraz and Isfahan that is full of vitality.
