About Shri Rameshwara Swami Temple
Standing on an elevated land, just besides the Tunga river bank, this temple is a major Mujrai temple of Thirthahalli Taluk. The temple houses a Shiva Linga that is said to be installed by Sage Parashurama himself. The linga in Rameshwara Temple of Thirthahalli is known as “Mood Linga”. Outside the sanctum sanctum there are idols of Durga and Ganapathi. Ramatheertha, the holy spot where Sage Parashurama washed his Parashu (Axe) adorns adjacent to the temple on the River bank.
Around Ramatheertha there are other theerthas that are equally important- Chakratheertha, Shankatheertha, Gadatheertha and Padmatheertha. Near Ramatheertha, there is a stone mantap called “Rama Mantapa” and just in front of this mantap there is a stone baser. “Jogigudda” with a cave in it, where the Jogis (Wandering Ascetics) used to sit and meditate, is situated between Ramatheertha and Chakratheertha.
Sri Ramachandra Devara temple was basically a private institution situated on the banks of the river Tunga in Somashekara Agrahara in Thirthahalli. The temple was constructed and dedicated to Sri Ramachandra by one Samagodu Ramappaiah in 18th century to fulfil the wish of his father Sri Thimmappaiah who had a pious wish to construct a temple and dedicate it to Sri Ramachandra.
Over a period of time the temple came to be known as Sri Kodandarama Temple. Later it was taken over by the Mujrai Department. Ever since the temple was constructed, the descendants of Thimmappaiah have been worshipping in the temple and conduct other ceremonies. Sri Vittal Temple in the same premises was built by one Damarasa Pai, who was a minister during the rule of Ikkeri and Keladi Kings in the 15th Century. Since then the descendants of Damarasa Pai have been conducting Poojas and other ceremonies in the temple. At present, Sri Raghavendra Bhat and his brothers are performing rituals in the temple.
