An incident is narrated related with the formation of this temple. According to it, every Tuesday merchants from Coimabatore came to this region to trade with the local tribals. On one of this day, two sisters travelling from north, reached the market. They had divine looks and manners. When they asked for a place to stay, they were told to stay under a nearby tree. They did not know that the sisters were Goddesses. A lightning or flash of light appeared near the tree and the sisters disappeared. Then the people understood that the sisters were divine forms and built a temple for Goddess Kaliamman and Mariamman together. It is the Mariamman temple seen today. It is the only place where both goddess are seen together. Even today people gather at market on Tuesday and worship Goddess Mariamman on their way returning from market. Temple Festival
