The Bast (Sanctuaries) Around the Holy Shrine
The space after the courtyards which leads to the avenues around the holy shrine is called as Bast. The Basts situated after the courtyards are the frontal limits for safeguarding the buildings of the holy shrine. It is also the shelter house for the pilgrims during any occurence of any accident. It is also the place where the pilgrims get ready to visit the holy shrine and thus the places for ablution (wuzukhaneh) are also situated in these Basts.
