The story
This rock-cut shrine is dated by most sources to the 9th century, though Trawell says 8th. Epigraphic evidence suggests it was a Jain temple until about the 9th century, and during the time of Rajaraja Chola it appears to have passed into Hindu hands and become a Shiva shrine. Some sources credit the Ay ruler Vikramaditya Varaguna with its excavation. It is a protected monument under the ASI's Thrissur circle. Its surviving murals on the northern wall of the inner hall have been studied by scholars, including Ajit Kumar in a 2016 paper.
