Kaviyoor Mahadeva Temple is the oldest Shiva temple in Kerala, located 6 Km away from the town of Thiruvalla. This temple is famous for its one of its kind gable style of architecture. It is characterised by the building with a triangle formed by the slanting of roof. Built over 100 years ago, this temple is among oldest temples of South India and is commonly called as Thrikkaviyoor Mahadeva Temple. People magnanimously pray to lord Mahadev and Parvathi Devi in this temple.
Devotees swarm to Kaviyoor in the months of December and January during the temple festival and also during the Hanuman Jayanti. The ancient carvings gracing the walls of this temple belong to the 16 century and are mostly texts from the epic scriptures of the Ramayana and Mahabharata. One can observe the extensive use of wood in the buildings of the temple. This unique structure with ancient carvings is truly an architectural marvel and will delight a traveller.
