1,500-year-old stepped reservoir unearthed on Elephanta Island, revealing ancient maritime contacts
Archaeologists from the ASI's Mumbai Circle have unearthed a 1,500-year-old stepped reservoir on Elephanta Island near Mumbai, described as a "remarkable engineering work." The massive T-shaped structure, measuring 14.7m long and 6.7m-10.8m wide, has 20 exposed steps built from non-local stone blocks. This discovery is significant as the island's rocky nature prevents water seepage, making water storage crucial. The excavation, ongoing since November 2025, has also yielded a brick dyeing vat, storage pot, terracotta figurines, glass and stone bangles, beads, stone anchors, and about 3,000 amphorae sherds of Mediterranean and West Asian origin. Importantly, 60 copper, lead, and silver coins, some identified as belonging to the 6th-century Kalachuri dynasty ruler Krishnaraja, confirm the island's long-distance maritime contacts.
