Situated atop the Nagadri Hill, is a gigantic 101-foot Shivalinga encircled by Kaalasarpa, which has become a popular destination for devotees to offer prayers to Nagakoteeswara Swamy. With one crore Shivalingas made out of anthill mud, the shrine is believed to be so powerful that just by pradakshina, one can attain salvation from the ill-effects of the Naga Dosha, Kuja Dosha and Kaalasarpa Dosha.
