Chak Chak

Chak Chak or Chek Chek (‌, lit. 'Drip-Drip'), also called Chāhak-e Ardakān (lit. 'Well of Ardakan') or Pīr-e Sabz (lit. 'The Green Pir'), is a location in the Yazd province of Iran. Located near the city of Ardakan, its existence was noted in the 2006 Iranian census. The site consists of a "pir" (a pilgrimage site for Zoroastrians) perched beneath a towering cliff face in the desert of central Iran. It is the most sacred of the mountain shrines of Zoroastrianism, which was formerly the majority and official religion of the Iranian nation. Each year, from 14 to 18 June, thousands of Zoroastrians from Iran and India, among other countries, flock to the site's fire temple.
