Sangam is a Sanskrit word for confluence. Sangam at Prayag(Allahabad) is at the confluence of river Yamuna and Ganga and is a sacred holy site for Hindus. According to Vedic literature and myths it is called Triveni Sangam because three rivers meet up here namely the holy Ganga,Yamuna and mythical Saraswati which is believed to be flowing beneath the surface. At the time of churning of sea (Samudra Manthan) by Gods(Suras) and the Demons(Asuras) few drops of amrita(Holy nectar that makes a mortal immortal)fell at four different parts of the subcontinent during a fight between Gods and Demons over it. That places are Hardwar, Nasik, Prayag and Ujjain and are considered holy and MahaKumbha Mela is organised once in 12 years. Billions of pilgrims, tourists,ascetics,sadhu/sant(holy men) visit Prayag at the time of month long Kumbha for taking holy dip at sangam and perform religious rituals and ceremonies. Also Magh Mela is organised annually on January-February(Magh month of Hindu Calendar) and millions visit to take holy dip at sangam.
