The temple dedicated to Saint Kapil Muni is the principal attraction of Sagardwip. After a holy dip in the water, pilgrims go to the temple to offer prayers to the Saint.
The temple, along with four other temples got destroyed in a storm in 1960s. The Kapil Muni Temple was the only one that got restored. It is believed that after attainting salvation, Kapil Muni came back and passed on the divine knowledge to his mother, on how to attain Nirvana. Kapil Muni is therefore worshipped by people to help them absolve their sins.
