Ashkaft Yazdan Cave was the place for keeping the fire that was transported from Nahid Fire temple to Haftad Village near Aqda. Then it was transferred to Turkabad in Ardakan and after 30 years of protection in Ashkaft Yazdan Cave, it was finally brought to Yazd in 1325 solar year and is now lit in Bahram Fire temple in Yazd City.
This ancient cave is near Aqda and is one of the holy caves of Zoroastrians. The entrance of the cave is very difficult to pass. However, there is a vast area inside the cave that can contain thousands of people. Several small and big pools and building structures can be seen inside it. Lots of ashes can be seen in the cave which show that the holy fire used to be protected in these caves for years.
