Sixty-six km to the east of Tehran, to the right of Tehran-Firuz Kuh road, Damavand is a small town set in a closed-off and well-watered valley below the foothills of Mount Damavand whose cone is not visible from this place. During the summer months, its populations are swollen by an influx of holidaymakers. Archaeological excavations carried out in the site of the modern town of Damavand have shown its occupation since the Neolithic times fifth millennium BC. The origins of the town go back to the Sassanian period. In the historical districts of the town as well as in its neighboring villages, there remain some relics belonging to the beginning of the Islamic period, the 11th century AD, and the Seljuk period. 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 a new 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 southeast of the mosque, is thought to date from the Seljuk period. The Imamzadeh Abdollah, near the northeastern edge of the town, must date form 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.
