On a desert plain several kilometres southwest of Yazd, two large circular stone platforms rise from the gravel — the dakhmas, or Towers of Silence, where Yazd's Zoroastrian community practised sky burial until the mid-20th century. The towers themselves are off-limits, but you can walk up to and around them, and the barren landscape and mountain backdrop make for a striking destination.
Beside the towers are the ruins of the associated buildings: ossuaries where bones were collected, wells, and the caretaker's quarters. The whole site sits in a wide, quiet valley with excellent views of the surrounding desert. A taxi from central Yazd takes about 20 minutes; many travellers combine the visit with the Zoroastrian village of Cham nearby. Allow at least two hours for the site and surroundings.
