Kaboud Mosque of Tabriz, Iran

I received my one and only Iran card from moonlessnight of Canada for Another Country RR, Group 125. Now I searched for this mosque and just learned that it is one UNESCO's tentative list for a WHS. UNESCO website says, "This mosque is one of the precious works of Islamic period (the Temurids) and is known as turquoise of Islam as it has been built of turquoise-colored bricks. It is one of the most beautiful buildings of Timurid period. Geographically, it has been located in a cold climatic condition, and for the same reason, it has no quadrangle. The remainder consists of a tomb and a mosque that its dome is double layered".
