Located 29 km from the head quarters of Thirunelveli and surrounded by lush green fertile land, Nanguneri is a panchayat town renowned for the famous Vaishnavite temple commonly known as Totadri Mutt dedicated to Lord Vishnu. Also known by the names such as Medini and Sri Nivasam, Nanguneri is considered as the birth place of Sri Devi, one of the consort of Vishnu. The temple is one among the eight Swayamvyaktha Kshtrams.

The presiding deity of Lord Vishnu in the form of Totadri Naadhan can be seen in the sitting posture on the couch and canopy of Adi Shesha, with his two consorts Sri Devi and Bhoo Devi on the two sides besides the celestial dancers Tilottama and Urvashi in attendance with fans in hand. Ennai Kinaru (oil well) in this temple is very famous and devotees consume this oil to get cured of diseases. The temple is known by different names like ‘Bhooloka Vaikuntham’, ‘Totadrikshetram’ and ‘Vanamamalai’. The main festivals of the temple are celebrated in the Tamil months of Panguni (March-April) and Chitra (April-May).
