Dwaraka is of importance, because Sri Krishna lived there. And also because it was drowned soon after his death.

  • One Kusasthali was founded by Sri Rama’s son Kusa.
  • One Kusasthali was founded by Raivata the father-in-law of Balarama. This became Dwaraka (Vishnu Purana)

Raivata Kakudmin (Balarama’s father-in-law) later ruled here. Sri Krishna commissioned Dwaraka to be built over Kusasthali.

Excerpts from this link (Recent Dwaraka Underwater Explorations.)

“Historicity of Dwarka

The city of Dwarka has been under investigation by the historians since the beginning of the 20th century. Although a very famous religious and maritime centre, the exact location of this port city was under debate since long. Several literary references, especially from the Mahabharata have been used to suggest its exact location. Pargiter was the first to suggest that Dwarka was located near the Raivataka mountain; he also mentioned that it was constructed on the remains of Kusasthali. Pusalkar suggested that Dwarka of the modern times is the original Dwarka mentioned in the Mahabharata. Sankalia has also strongly argued that the modern-day Dwarka is in fact the same as the one that existed during the Mahabharata period. The earliest epigraphical reference to Dwarka comes from the Palitana copper plate of Garulaka Simhaditya dated to 574 AD . The unknown Greek writer of the Periplus of Erythraean Sea makes a mention of Baraca , which has been identified as modern Dwarka. In Ptolemy’s Geography, Barake is the name of an island in the Gulf of Kanthi  and the reference is most likely being made to Dwarka. ”

“… Underwater structures particularly semicircular ones have been described as the remnant of bastions of the Fort wall17 as in the case of Harappan, historical and mediaeval period. However, the absence of any other artifact, like pottery, suggests that this may not be a habitational site. Underwater explorations in Bet Dwarka and Poompuhar yielded a large number of pottery from 5 to 8 m water depths, indicating that any submerged habitation should have at least pottery, which is absent in Dwarka. Therefore, it may be argued that the structures found off Dwarka might not be the part of any habitation. Findings of the large number of stone anchors along with these structures suggest that the boats were anchored here.”

“… Study of the structures of protohistoric and historical period in the nearby localities such as Okhamandal suggests that the blocks used for the construction are different from those found in Dwarka waters. Excavations at Nageswar, a protohistoric site, yielded several structures of small irregular blocks. Similarly excavations at Bet Dwarka revealed that small irregular blocks dating back to the early historical
period were used for construction. Structures from Dwarka waters are found to be uniformly dressed with
provision for dowels. Explorations brought to light a rectangular stone block bearing Gujarati script, which suggest that these structures are of recent origin. The anchors belong to a wide time range, between historical period to 15th century AD All of these evidence argue that the
harbour at Dwarka was in use since the historical period and it must have been repaired and reused during the later period.”

“… Conclusion
The underwater structures lying off Dwarka are the remains of a jetty. It is difficult to date these structures precisely, however the binding material suggests that it may be of the late medieval period. Discovery of a large number of stone anchors suggests that Dwarka was an important port since the historical period and continued till late medieval period. Existence of a wide variety of anchors may suggest that different types and sizes of boats from different regions used to visit Dwarka harbour. The available evidence suggests that natural factors like coastal erosion are primarily responsible for the destruction of the port of ancient Dwarka.”
