Ayyanar temples are not architecturally elaborate but are signs of continuing traditions — of craft, myths, rituals and caste politics.
Ayyanar is a regional Tamil male deity who is popular among the rural social groups of South India, specifically Tamil Nadu. In the old Tamil literature he is mentioned as Sathanar and in Vedic stories, Ayyanar is considered as one of the several local manifestations of Sastha.
The deity is also popular among vast majority of South Indian & Sri Lankan (read Dravidian) Hindus and some Buddhists in Sri Lanka. He, along with his two female consort deities, is the central deity surrounded by 21 associate folk deities identified as the Kaval Deivam (guardian angel).
