Arg of Tabriz, also known as Arg-e Alishah, belongs to the Mongolian Ilkhanate dynasty, namely 700 years ago. According to historians Alishah, who was a minister of the Ilkhanate dynasty, ordered to construct the vault of this citadel 4 meters higher than Taq Kasra (the vault of Kasra). Arg of Tabriz has experienced many ups and downs during its lifetime including resistance to the attack of the Russians and the destruction of a large part of its walls under the pretext of the construction of Mosalla of Tabriz (a place where Muslims pray in groups).
Nowadays only the Southern part of the Mihrab (a semicircular niche in the wall of a mosque that indicates the qibla; that is, the direction of the Kaaba in Mecca and hence the direction that Muslims should face when praying) of this 30-meter building remains, which is restored and protected by The Cultural Heritage, Handicrafts and Tourism Organization.
Arg of Tabriz is located near Tabriz Municipality Palace and Historical Houses such as Behnam House and Blue Mosque of Tabriz.
