The fire inside is said to have been burning since
about AD470. Visible through a window from the
entrance hall, the flame was transferred to Ardakan
in 1174, then to Yazd in 1474 and to its present
site in 1940.
Above the entrance of this building, there is
symbolic bird-man symbol of Zoroaster. One hand
holds a ring, which symbolizes loyalty, while the
other hand is held up to indicate respect.
The wings have three layers of feather, reflecting
the Zoroastrian belief that you should think, speak
and act decently.
