Arg of Tabriz, is the remnants of a large acropolis fortificationand city wall in downtown Tabriz. Ark's structure is visible from far distances in downtown of Tabriz, if not blocked by newly high raised building.
The structure was initially a compound, containing a great vaulted mosque, adjoining prayer halls and libraries, a vast courtyard containing a huge reflecting pool, and a mausoleum-- all surrounded by a containing wall. It was built in 14th century during the Ilkhanate era. The point of pride for the building was that its vaulted ayvan was larger than the famous historic vault of Chosroes/Kisra or the Taq Kisra at Ctesiphon/Mada'in.
