The City of Yazd is located in the middle of the Iranian plateau, 270 km southeast of Isfahan, close to the Spice and Silk Roads. It bears living testimony to the use of limited resources for survival in the desert. Water is supplied to the city through a qanat system developed to draw underground water. The earthen architecture of Yazd has escaped the modernization that destroyed many traditional earthen towns, retaining its traditional districts, the qanat system, traditional houses, bazars, hammams, mosques, synagogues, Zoroastrian temples and the historic garden of Dolat-abad.
The name is derived from Yazdegerd I, a Sassanid ruler of Persia. The city was definitely a Zoroastrian center during Sassanid times. After the Arab conquest of Iran, many Zoroastrians migrated to Yazd from neighboring provinces. By paying a levy, Yazd was allowed to remain Zoroastrian even after its conquest, and Islam only gradually became the dominant religion in the city.
Because of its remote desert location and the difficulty of access, Yazd remained largely immune to large battles and the destruction and ravages of war. For instance, it was a haven for those fleeing from destruction in other parts of Persian Empire during the Mongol invasion. In 1272 it was visited by Marco Polo, who remarked on the city’s fine silk-weaving industry. In the book The Travels of Marco Polo, he described Yazd in the following way:It is a good and noble city, and has a great amount of trade. Historic City of Yazd was inscribed on the world heritage list of UNESCO in 2017.
