Yazd has a history of over 5,000 years, dating back to the time of the Median empire, when it was known as Ysatis or Issatis. The present city name, however, 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.
Yazd is an important centre of Persian architecture. Because of its climate, it has one of the largest networks of qanats in the world, and Yazdi qanat makers are considered the most skilled in Iran.
To deal with the extremely hot summers, many old buildings in Yazd have magnificent wind towers, and large underground areas.
The city is also home to prime examples of yakhchals, which were used to store ice retrieved from glaciers in the nearby mountains. Yazd is also one of the largest cities built almost entirely out of adobe.
