The sacred mausoleum of Imamzadeh Hussein, the immediate son of Imam Reza (AS) – (death 816A.D.) has always been a religious place for pilgrims since the third century on, so that many of the scientists, eloquent speakers and great men of the city are buried there.
The glorious building of the mausoleum was totally damaged during Mogul invasions and conflicts of the Safavid era. After that the place was renovated again and except the precious wooden shrine- that is a masterpiece of inlaid works and reticular fretwork left from 1403 A.D. -the rest of the building is left from Safavid and Qajar era.
The large precinct of Imamzadeh which along with its 52 small verandas have surrounded the tomb is an excellent example of tile work and architecture in Qajar era.
The edifice in the middle of the precinct is a hexagon decorated both with mirror works and aigrette -shrub patterns and with an elliptical paneling in plaster and precious tile works.
