On June 17, 2004 the BBC News reported, "Members of Iran's dwindling Zoroastrian community are making their annual pilgrimage to the temple in the rocky mountain of Chakchak. The desert site near the central city of Yazd is holy to the minority whose numbers are said to have halved to 22,000 since the 1979 Islamic revolution. It is believed the last Zoroastrian princess sheltered from the Muslims in a cave on Chakchak in AD 640...Yazd is the historic capital Zoroastrianism, considered by some to be the world's first monotheistic religion and a profound influence on Judaism, Christianity and Islam...Legend says the Chakchak mountain opened up and received Nikbanou [daughter of the last Zoroastrian king] - closing behind her at a spot marked by a fresh water spring. Pilgrims have long since removed a colourful rock believed to be a petrified cloth that was all that was left of Nikbanou. Today, pilgrims make their way up the towering rocks, following hundreds of steps to a cave where they pray and drink clear water from a spring."
