Introduction to the Tower of Silence: The Zoroastrian tower of silence was built on a mountain. Long ago, after Zoroastrian believers died, they put their bodies here to hold religious ceremonies and then let them be eaten by passing vultures and crows. Similar to Tibetan sky burials. At the foot of the mountain are some classical Zoroastrian buildings. This is the highest point in Yazd, and you can see the entire city of Yazd from a distance.
