A fortress on the summit of an isolated rocky hill in the Alburz mountains, situated some 18km west of Damgan in northern Persia.
Thrust forward into a sloping plain, the hill of Gerdkuh rises about 300 metres above its base, and seen from the south, the access direction to the site, the hill appears dome-shaped; hence its name Gerdkuh (round mountain). In medieval times, Gerdkuh was also known as Dez-i Gonbadan which Islamic sources identified with the one mentioned in the "Shahnama" (ed. Vullers, III, pp. 1550, 1552, 1635, 1643, 1671;'Mujmal, p. 52; Rashid al-Din, 1959, p. 117; Mustawfi,'Nuzhat al-qulub, text p. 161, tr. P. 158; idem,'Tarikh-i guzida, p. 93).
