The Dockyard at Lothal

Record summary

Lothal, a Harappan-period settlement in Gujarat, includes a large brick-lined basin widely interpreted as a dockyard or tidal installation. The feature has become central to discussions of Indus maritime trade, hydraulic engineering, and the movement of goods through the Gulf of Khambhat. Its precise function remains contested: proposals include a dock, reservoir, or water-management structure, with debates involving ancient shoreline change and local hydrology. The site is valuable precisely because engineering interpretation must be tested against sediment, elevation, settlement, and regional coastal evidence.
