Dwarka, one of the best-studied underwater sites in India, has commanded much attraction, also because the site is considered as one of the four Dhamas (sacred place for pilgrimage) of the Hindu religion. According to ancient Sanskrit literature, the Lord Krishna founded the holy city of Dwarka, which subsequently got submerged under sea.
Marine archaeological explorations off Dwarka have brought to light a large number of stone structures, which are semicircular, rectangular and square in shape in water depth ranging from inter tidal zone to 36 metres (120 feet). They are randomly scattered over a vast area. Besides these structures, a large number of varieties of stone anchors have been noticed along the structures as well as beyond 36 m water depth.
These findings suggest that Dwarka was one of the most busy port centers during the past on the west coast of India. The comparative study of surrounding sites indicates that the date of the structures of Dwarka may be between Historical period and late medieval period.
