Thirunelly temple is 3000 years old and is near the Papanashini stream. This temple is devoted to Vishnu. This is constructed with 30 granite columns to protect it. There is a bridge from the Papanashini stream coming to the temple. This is of great help to the Thirunelly temple as the Papanashini water is used for the temple directly for its precincts.
Towards the southern side of the Thirunelly temple, a pond called Panchatheertha is sited. This is named Panchatheertha as it is believed that five rivers met at this point. Generally, this pond has impenetrable undergrowth, but during summers this pond becomes waterless.
