Tarikhaneh Mosque is in fact the oldest mosque in Iran belonging to the 1st century after arrival of Islam which still preserves its original shape. Tarikhaneh andNa'in Mosque in Na'in are the only mosques in the Islamic World which resemble the Medina Mosque. This mosque was built during the 8th century AD by imitatingRoman, Iranian and Arabic architecture. This is an Arabic design but the building material and architecture is Sassanid. This leads us to believe that originally it had been a fire temple during the Sassanid period, and later the mosque was built over its ruins. One column resembling Sassanian architecture at the eastern wing is a proof of this assertion.

Tarikhaneh Mosque is equipped with a square yard and a gallery with 18 columns facing the Qiblah and the three sides of the yard are surrounded by porticos. The minaret rising over the mosque is said to belong to Seljuks and the tiled inscription over the minaret is in fact the oldest tile work in Islamic architecture.

The prefix "Tari", a Turkish or Mongol term, means God and "khaneh" is Iranian word for house so the word means the house of God.
