Lothal
Lothal: home of the world's earliest known dock. IVC port city in Gujarat with evidence of maritime trade to Mesopotamia.
Evidence of sophisticated maritime trade networks spanning the Arabian Sea to Mesopotamia. Discovered by S.R. Rao in 1954.
Overview
Lothal is a port city discovered and excavated by S.R. Rao starting in 1954. Its most significant feature is a trapezoidal basin measuring 37m × 22m × 4.15m, which Rao identified as the world's earliest known tidal dock — a claim debated by some scholars who argue it was an irrigation tank. The dock included a sophisticated sluice gate and spillway channel connecting it to the Sabarmati river tributary, allowing ships to enter at high tide. Lothal's bead-making factory produced carnelian, agate, and steatite beads that have been found in Mesopotamian and Egyptian sites, confirming long-distance maritime trade. Rice husk embedded in pottery and kiln walls provides early evidence of rice cultivation in western India. The site's warehouse, with brick-lined loading platforms and a bitumen-sealed floor, shows organized trade infrastructure.
