The Mangala Devi Kannagi Temple is a historic stone structure situated at an altitude of approximately 1,337 meters on the border of Tamil Nadu and Kerala. It is dedicated to Kannagi, the heroine of the Tamil epic Silappatikaram, who is worshipped here as the Goddess of Chastity. The temple is built in the Pandyan architectural style using granite blocks. Due to its location within the Periyar Tiger Reserve, the site is strictly regulated by forest authorities. Access to the temple is restricted to a single day each year, typically coinciding with the Chitra Pournami festival. The structure stands in a remote, high-altitude clearing surrounded by dense shola forests and grasslands.
