Sittanavasal Cave (also, Arivar Koil) is a 2nd-century Tamil Śramaṇa complex of caves in Sittanavasal village in Pudukottai district of Tamil Nadu, India. Its name is a distorted form of Sit-tan-na-va-yil, a Tamil word which means "the abode of great saints" (Tamil: சித்தன்னவாசல்). Ancient structures such as Gol Gumbaz, Talagirisvara temple and this one are claimed to be relatively unappreciated. Archaeological Survey of India has listed Sittanavasal Cave in the list of "Must See" Indian Heritage.
