Archaeological excavations carried out in the site of the modern town of Damavand have shown its occupation since the Neolithic times (5th millennium BC).

The most important amongst these is are the Jom'eh Mosque and its minaret, of the same period, however restored in later periods (particularly during the Safavid rule) and thus turned Into anew building void of any historical significance. The mosque's circular and simple brick minaret, which rests upon a rectangular brick base, is the only remaining relic of the structure.

Traces of a Kuffic inscription and of other decorations, in the 11th-century style, remain to this day upon the minaret. At Damavand there are also two funerary towers of the kind found so abundantly in the Caspian region. The Imamzadeh Shams od-Din, to the south-east of the mosque, is thought to date from the Seljuk period The Imamzadeh Abdollah, near the north-eastern edge of the town, must date from the beginning of the 14th century, although the carved wooden doors are of a later date than the building. Two barred windows were recently added on the south.
