Ateshkadeh in Yazd
The main Zoroastrian fire temple, Ateshkadeh (in a small garden east of Ayatollah Kashani Street) is open Saturday to Thursday from 8 to 11 and 2:30 to 4:30, except on public holidays.
There is no entry fee, but donations are welcome. The temple building is surrounded by evergreen trees and a large round water basin in the courtyard, in whose water the temple is reflected - a beautiful subject for an artistic photo.
The sacred flame, clearly visible in the interior behind a pane, has been burning since 470 AD, according to the explanations of a Zoroastrian priest, and was moved here from its original location in 1940. It attracts Zoroastrians from all parts of the world, so you may meet someone who can explain details to you in English.
There are paintings hung on the walls, one of which depicts Zoroaster. From an architectural point of view, there are similarities between this temple and the fire temples of the Iranian Zoroastrians.
There are also numerous other Zoroastrian sites such as Qaleh Assadan (Lion Fortress), a little northeast of Yazd and the most important - Chak Chak (see below) 52 km north of Yazd.
