Yazd is located in the deserts of Iran, close to the Spice and Silk Roads. It is a living testimony to intelligent use of limited available resources in the desert for survival. Water is brought to the city by qanat system.
Each district of the city is built on a qanat and has a communal centre. Buildings are built of earth. The use of earth in buildings includes walls, and roofs by the construction of vaults and domes. Houses are built with courtyards below ground level, serving underground areas.
Wind-catchers, courtyards, and thick earthen walls create a pleasant microclimate.
Partially covered alleyways together with streets, public squares and courtyards contribute to a pleasant urban quality.
The city escaped the modernization trends that destroyed many traditional earthen cities.
It survives today with its traditional districts, the qanat system, traditional houses, bazars, hammams, water cisterns, mosques, synagogues, Zoroastrian temples and the historic garden of Dolat-abad.
The city enjoys the peaceful coexistence of three religions: Islam, Judaism and Zoroastrianism.
