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, Lord Krishna founded the holy city of Dwarka, which subsequently got submerged undersea.
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 the intertidal zone to 36 meters (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 with the structures as well as beyond 36 m water depth.
