A prominent feature of Sarayan county is the abundance of active Ab-Anbars. According to some researches, the Grand Mosque of Sarayan dates back to Safavid period. Its porch of 13 meters high is adjacent to two prayer halls (Shabistan). The courtyard of the Mosque is enclosed with a wall covered with shallow arcades.
This wall is known to be related to Qajar era. The beautiful mihrab (prayer niche) of the Mosque is decorated with carved stucco and Surah al-Fatiha is inscribed on it. Moreover, the vault of the inner part of mihrab is decorated with Mogharnas.
Indeed, there are very beautiful Mogharnas at the top of the mihrab and the porch roof, which has made the face of the porch so graceful and elegant. The façade of the porch is trimmed with bricks design and the western prayer hall has beautiful decorative schemes on the corners.
