The chief engineer Sayyid Karar al-Mousawi said, “We installed twelve doors of 3.20m long, 2.25m wide, and 10cm thick. Between each of these doors, there is a window made of silver and wood that is 5.10m wide and 6m long.”
“These doors were made in special workshops in the Holy Shrine of Imam Ridha (PBUH). They are made of the finest wood in the world like beech, walnut, etc. Moreover, we decorated and colored the doors and the area around them,” he added.
