The history of the Uchi Pillaiyar Temple is intertwined with the legends of the Rockfort. According to local lore, the rock was used by the Pallavas and later the Nayaks. Legend says that Lord Ganesha, in the guise of a young boy, tricked the demon King Ravana to prevent him from taking the idol of Lord Ranganatha to Lanka. Ganesha placed the idol on the rock, and it became immovable. Enraged, Ravana tried to destroy the rock, resulting in the formation of the temple. The Nayaks, particularly Vishwanatha Nayak, significantly contributed to the temple's structure and development during their reign in the 16th century. Over the centuries, the temple has become an important religious and cultural symbol of Trichy.
