The Mangala Devi Kannagi Temple is believed to be over 1000 years old. Kannagi, the deity, is a symbol of chastity and justice from the Tamil epic Silappathikaram. Legend says she sought refuge in the hills after destroying Madurai city with her curse. The temple's location within the Periyar Wildlife Sanctuary adds to its historical and ecological importance. It stands as a testament to the region's rich cultural heritage and its connection to ancient Tamil literature and traditions. The limited access and the annual festival contribute to the temple's unique aura and attract devotees and tourists alike.
