Allah Balaghi Fountain is one of the natural attractions and sights of Qazvin, which is located in the outskirts of Mahan village. They say that this mineral water spring is useful for removing kidney stones and removing stones from the bladder and urinary tracts, and every year many patients from nearby areas travel to this area. The residents of the region also use the water of this spring for medicinal and therapeutic purposes. Due to the fact that proper tourism infrastructure is not provided for the use of this spring, we only see their traditional use.
