Chamakkavu Devi Temple near Venmoney is currently a Hindu Temple, but historically this temple was a Buddhist place of worship, which was transformed initially into a Vishnu temple (then known as Sharnga-kavu) and later into a Devi temple. The annual chariot festival and other traditions correspond to the old Buddhist practices of \"kettu kazhcha\", which was assimilated into Hinduism in Kerala. The old Buddhist families that worshipped at this temple are said to have moved to a nearby \'kavu\' called Vavvara. The Vavvara kavu was owned and maintained by the Elavanthi family. M. C. Narayanan of Kallumala used to be the head of the clan that maintained the Vavvara Kavu and legendary family related to the Chamakkavu temple (the old Buddhist shrine).
