Nagmandir of Berinag is an important shrine located in the Berinag village. This is a snake temple bordered by trees and ravines. It is believed that the Pants of Maharashtra came here in the 14th century to settle down and they saw various colourful snakes in large numbers in this place. This led to the construction of a snake temple which was named 'Nagmandir'. According to another popular belief, after defeating the Kalinag, Lord Krishna advised him to leave the River Yamuna. After that Kalinag, accompanied by many followers, possibly came to this place.
