Dashtadem fortress is located in a homonymous village near Talin town. It appears to be one of those medieval fortresses of Aragatsotn province, that were built for protecting Ararat Plain from attacks. The base of the fortress was founded during Urartian period. The citadel was built by Kamsarakan princes, who carried out large-scale construction works in the province. After the fall of Bagratuni Kingdom of Armenia, most of the territory went under the control of Seljuq sultans. At the end of the 12th century the governor of Ani capital – Sultal ibn Mahmoud, built pyramids with a semi-circular and polygonal plan there, and left an Arabic script about it. Zakaryan princes built the walls with semi-circular towers around the fortress, as well as a single-nave domed church near the northern wall. At the beginning of the 19th century Hussein Khan of Yerevan built enclosures with 8-angled towers and quite thick walls, thanks to which, the fortress became the largest within the territory of the Republic of Armenia.
