It is located in Ghalaviz Village and 52km far from south of Zanjan. In archaeological researches, there was discovered a complex including a mosque, temple and castle in foothills of the western mountains of Zanjan. The plan of the mosque is a small square which is built of travertine stone. There is an inscription installed on this mosque also. The mehrab of the mosque is fully white and is designed with the names of Imams of Shia. Also some of Islamic drawings have made the mosque more attractive. there is no information about the roof and ceiling of the mosque, but we guess that it had been covered by dome in past.
