Parsis or Zoroastrians build
Fire Temples as places of their worship. There are three grades of Fire Temples, Atash Behram, Atash Adaram, and Atash dadgah. The holiest Fire Temple in India is the Atash Behram at Udvada, about one hundred miles from
Mumbai. Here the Sacred Fire brought by Iranian refugees from Iran has been continuously burning since 1741. Consecrated around 790 AD, the Fire temple, Atlash Behram at
Sanjan, is the earliest fire temple in India.
