Mariamman temple, Ooty, Hindu temple in Ooty, India.

Mariamman Temple stands near the market in Ooty, Tamil Nadu, and is dedicated to Mariamman, the local rain goddess. It is the only place where the goddesses Mariamman and Kaliamman are seen together, according to the temple legend.

According to local legend, two divine sisters came to the Ooty market, where merchants from Coimbatore traded with local tribes every Tuesday. Told to stay under a nearby tree, they vanished in a flash of light. The people then built a temple to Kaliamman and Mariamman together, the only place where both goddesses are seen together.

Mariamman is also called Seethala Gowri or Mahamaayi, and is regarded as a form of Kali. On Tuesdays, people worship her at the market on their way back from trading, a custom that continues today. The temple is the only place where Mariamman and Kaliamman are seen together.

The temple stands near the market in Ooty, so it is easily reached on foot from the town centre. Tuesday is the day traders and villagers gather at the market and worship Mariamman on their way home, making it the busiest day. During the April festival, devotees walk barefoot over burning coal and offer lamps made from ground rice.

It is the only place where the goddesses Mariamman and Kaliamman are seen together, according to the temple legend. Devotees still gather at the Ooty market on Tuesdays and worship Mariamman on their way back from trading, as merchants from Coimbatore once did.
