*****************************************
A Dakhma (Persian: دخمه‎), also known as "Tower of Silence" in English, is a circular, raised structure used by Zoroastrians for exposure of the dead, particularly to scavenging birds for the purposes of excarnation.

The common dakhma or dokhma (from Middle Persian dakhmag) originally denoted any place for the dead.
Similarly, in the medieval texts of Zoroastrian tradition, the word astodan appears, but today that word denotes an ossuary. In the Iranian provinces of Yazd and Kerman, the technical term is deme or dema.
