Between the villages of Issa Abad and Maidanak of Khalajestan, flows a small river which has a small dam constructed by brick, gypsum and cobbled stones alongside.
This dam is the foundation of the Imamzadeh that has been constructed on it. From the external view the structure is octagonal, though internally it is a quadrangle, to each side of which is an area for the elite. Internally the walls are white washed and adorned with colored paintings, along with archaic arched sun-baked and colored tiles.
The alcoves within have changed the quadrangle into a circular shape. In front of the mausoleum and under its porch is a door with old inscriptions related to the Safavid era. Amidst these inscriptions the name of ‘Hazrat Ali’ (AS) in the Tholth script can be observed. The beautiful dome of the mausoleum is also related to the Safavid age, and the same is adorned with tiles of various forms.
