Yazd

Marco Polo visited Yazd on his way to China and called "it good and noble city of Yazd". His comments still hold true today as the reputation of the citizens of this desert city for honesty and hard work remains undiminished. The architecture of Yazd is perhaps the most traditionally Persian to be found, preserved by the hot, dry climate and spared the devastation of the Mongols and other invaders.
  The badgers (wind-catchers) are seen from Kashan to the Persian Gulf but are most highly developed in Yazd. It is also the Centre for Iran's small Zoroastrian community, who seeking refuge from the invading Arabs found a safe haven within its fortified walls. There are many fire temples and other Zoroastrian places of pilgrimage which attract people of the faith from all over Iran. Outside Yazd are the two abadoned Towers of Silence ( Dakhma ), dating back to the 17th century, where until some 40-50 years ago the dead were carried there and left to decompose and be devoured by birds.
