The Center of Mosque Studies - Ja'me (central) mosque of Kermanshah is placed in Kermanshah city and is a relic from the late Zandiyeh period that was built in 1196 AH.
It was constructed apparently at the site of the former mosque by Alikhan Zanganeh, the governor of Kermanshah. What has remained from the mosque old building, is part of the pillared nocturnal area and the octagonal vestibule. The present nocturnal area, with the exception of the altar, has no special adornments. In the southwest corner of the building, are stairs which have been built for gaining access to the top floor that was perhaps used to be a part of a school.
At the beginning and to the right hand side of the entrance, there are three inscriptions dating 1200 AH. The same is relevant to matters concerning the purchase, sale and endowments of the said mosque.
