It is believed that more the Ettumanoor Mahadeva Temple and its surroundings were deserted for a long time due to the curse of Loma Maharshi. Later, Sri Vilvamangalath Swamiyar, during his travels, arrived at Ettumanoor, felt the divine presence of Shiva, and resumed worship. The Kalathoor Shiva Temple is said to have been built during this period when the Ettumanoor Mahadeva Temple was abandoned. Over time, the cave entrance to the original temple was closed, leading to the construction of the present structure.
