A major tīrthā situated on an island off the coast of Tamil Nadu, opposite Sri Lanka. Connected to the mainland by a causeway, it is supposed to mark the place where Rāma, after crossing back from Sri Lanka, did pūjā before a Śiva liṅga in order to purify himself for the killing of Rāvaṇa. The liṅga is housed in the 17th-century Rāmaliṅgeśvara temple complex, mostly built during the Nayaka period. A smaller temple holds Rāma's footprint; there is also a place where he is supposed to have bathed. Rāmeśvaram is counted as one of the four dhāmas, or ‘dwelling places’.
