The Fire Temple is the most sacred Zoroastrian site in Iran still in active use. Built in 1934 in a style that blends Art Deco with traditional Iranian architecture, the temple houses the sacred flame that Zoroastrians believe has burned continuously for over fifteen hundred years. The flame arrived in Yazd in 1940 after being moved multiple times to keep it safe from religious upheaval.
Non-Zoroastrians are welcome to visit the temple and view the flame through a glass-fronted chamber. The small museum adjacent to the fire room has explanatory panels on Zoroastrian beliefs and history in Iran. The building's hilltop location gives good views over the old city. Yazd remains one of the main centres of Zoroastrianism in the world, and the community here is welcoming of respectful visitors.
