The Submerged Artifacts of Dwarka: What Marine Archaeology and Carbon Dates Reveal About Coastal Gujarat

Along the Gulf of Kutch in western Gujarat, the intertidal zones of Dwarka and Bet Dwarka harbor material remains that have long drawn attention from both readers of epic literature and field archaeologists. Popular narratives often claim these submerged stone blocks and anchors belong to the legendary city of Krishna, assigning them ages as ancient as 7500 BCE.

Physical evidence collected from the seabed tells a different story. Systematic underwater explorations conducted by the Marine Archaeology Unit of the National Institute of Oceanography (NIO) and the Archaeological Survey of India (ASI) establish that these coastal structures belong to the mid-to-late second millennium BCE—a period corresponding to the Late Harappan and early Iron Age transition.

Underwater Investigations at Bet Dwarka

Offshore field research in the region began in earnest during the early 1980s under the leadership of marine archaeologist S.R. Rao. Diving operations off the coast of Bet Dwarka—an island situated in the mouth of the Gulf of Kutch—yielded a range of artifacts from the intertidal zone and shallow seabed.

Among the primary finds was pottery showing clear Late Harappan affinities, including lustrous red ware, perforated jars, and dish-on-stand fragments. Excavators also recovered a small, three-headed animal seal carved on shell, carrying artistic motifs that scholars compare to Persian Gulf trade artifacts of the second millennium BCE.

Further offshore, divers documented large dressed limestone blocks, walls, and scattered stone anchors. The anchors fall into three distinct types: composite stone anchors, triangular stone anchors, and ring-stones. Archaeologists note that these anchor designs match those recorded across ancient trade routes in the Indian Ocean, Mediterranean, and Red Sea.

What the Radiocarbon Dates Show

Tradition holds that Dwarka was a golden city built by Krishna that was engulfed by the ocean following his departure. To test whether the submerged physical remains matched the ancient literary timelines, researchers subjected recovered organic samples—including wood, shell, and charcoal embedded in intertidal strata—to radiometric testing.

Peer-reviewed radiocarbon analyses published by NIO researchers, including A.S. Gaur and Sundaresh, date the main habitation layers on Bet Dwarka to between 1600 BCE and 1400 BCE. Subsequent testing on shell samples and wooden artifacts from coastal trenches consistently placed the earliest human occupation of the island in the Late Harappan phase, rather than the early Holocene epoch.

Additional testing on the stone anchors revealed a much wider chronological range. While some triangular anchors align with second-millennium BCE maritime activity, many of the grapnel and composite stone anchors were dated to the Early Historic and Medieval periods, extending from the early centuries CE up through the 14th century CE. This spread indicates that the waters off Dwarka served as an active anchorage for millennia, accumulating lost equipment over centuries of continuous sea trade.

The Boundary Between Myth and Stratigraphy

Scholars debate how literary traditions intersect with these physical finds. S.R. Rao argued that the submerged structures at Bet Dwarka represented the historical core of the epic Dvaraka, suggesting that a major coastal flood or sea-level rise destroyed an ancient port around 1500 BCE, leaving behind memories that were later preserved and magnified in the Mahabharata and Purana texts.

Other archaeologists and historians advocate for a more cautious reading. Evidence shows that the submerged stone structures documented off present-day Dwarka consist largely of collapsed piers, sea walls, and ridge formations rather than a vast swallowed metropolis. The physical site displays the stratigraphy of a modest, fortification-walled protohistoric port town that exploited the natural shelter of the Gulf of Kutch.

By placing the site within the mid-to-late second millennium BCE, science firmly delineates the boundary between recited tradition and material culture. The submerged artifacts of Gujarat do not support claims of a ten-thousand-year-old city, but they do confirm that the waters off Dwarka were home to one of India's earliest recorded maritime trading communities.
