The temple “Kasi Viswanathar” is very close to the Mahamaham tank in Kumbakonam
The importance of this temple is the belief that it is here that the Nava Kannigais (nine maidens representing the nine rivers – Ganga, Yamuna, Saraswati, Kaveri, Godavari, Narmada, Krishna, Tungabhadra and Sarayu) arrive to bath in the Mahamaham tank on every 12 years once.
