This “desert Town” used to be an oasis-like stopover for camel caravans. Vast irrigation schemes, which draw water from underground springs and the surrounding mountains, have made Yazd into a green and fertile town. The town is famous for its traditional clay architecture and brick wind towers, which use the breezes to provide a kind of air-conditioning system for the houses. The region also offers a number of interesting sites: the mosques from the Islamic period and the Zoroastrian monuments, many of which are still used today, most notably the “fire temples” and the “towers of silence”. Every year, Yazd attracts thousands of visitors for various religious festivals besides the Iranian New Year (Now –Ruz, March, 21st). One of the most important Zoroastrian fire temples on a hill about 52 km outside Yazd attracts thousands of pilgrims in the month of June.
