Rameswaram, a town of British India, in the Madura district of Madras, on the island of Pambam in Palk Straits. It contains one of the most venerable Hindu shrines, founded, according to tradition, by Rama himself, which for centuries has been the resort of thousands of pilgrims from all parts of India. The great temple, with its pillared corridors 700 ft. long, is perhaps the finest example of Dravidian architecture.
