Thirukulambu is a sacred spot near
Thiruvumplavil Mahadeva Temple. The holy water flowing through the 'Thirukulambu' (holy hoof) is the source of Theerthakkulam, a pond situated north side of the temple. The water is believed to be the divine water from
Kashi.
A large number of devotees perform ‘pithru tharppan’ at this place during
Mahashivaratri and
Vavubali.
