Situated in a vast dry valley, 677 Km. south of Tehran. Yazd has a dry and semi-dry climate with hot summers and cold winters. In the past, without modern facilities, it was only the clever architecture of the building that enabled the people to tolerate the hot summer. The ventilation structures called baad girs (wind towers) were the most important means by which the interior became cool.
For this reason, Yazd was (and still is) called the city of baad girs. According to some historians, Yazd was founded by YazdegerdI (339-420 AD). Marco Polo, who came here on his way to China in 1272, called it “ The Good and Noble City of Yazd”.
