Rameswaram is significant for many Hindus as a pilgrimage to Varanasi is considered to be incomplete without a pilgrimage to Rameswaram. The town along with the Ramanathaswamy temple is one of the holiest Hindu Char Dham (four divine sites) sites comprising Badrinath, Puri and Dwarka. Though the origins are not clearly known, the Advaita school of Hinduism established by Sankaracharya, attributes the origin of Char Dham to the seer. The four monasteries are located across the four corners of India and their attendant temples are Badrinath Temple at Badrinath in the North, Jagannath Temple at Puri in the East, Dwarakadheesh Temple at Dwarka in the West and Ramanathaswamy Temple at Rameswaram in the South. Though ideologically the temples are divided between the sects of Hinduism, namely Saivism and Vaishnavism, the Char Dham pilgrimage is an all Hindu affair. The journey across the four cardinal points in India is considered sacred by Hindus who aspire to visit these temples once in their lifetime. Traditionally the trip starts at the eastern end from Puri, proceeding in clockwise direction in a manner typically followed for circuambulation in Hindu temples. The temple is one of the famous pilgrimage sites historically - the Maratha kings who ruled Thanjavur established chatrams or rest houses all through Mayiladuthurai and Rameswaram between 1745 and 1837 CE and donated them to the temple.
