On the southern outskirts of Yazd, there are two hilltop circular building, known as Dakhmeh-ye-Zartushtioon or Towers of Silence. To preclude the pollution of earth or fire, the bodies of the dead are placed atop a tower—a tower of silence—and so exposed to the sun and to birds of prey. Thus, "putrefaction with all its concomitant evils... is most effectually prevented.“
