Was the brick basin at Lothal, Gujarat, the world's earliest dockyard?
Disputed: evidence incompleteTechnology & engineering
Indian claim
S.R. Rao, who excavated Lothal (1955–1960), identified a large brick basin (over 200 metres long) with an inlet and spill channel as a tidal dock linked to the Sabarmati, the world's earliest known dockyard. The Government of India is building the National Maritime Heritage Complex there.
Evidence for the Indian claim
- A National Institute of Oceanography study reported marine microfossils, salt and gypsum in the basin, suggesting seawater entered it.
- A recent study (IIT Gandhinagar) suggests the Sabarmati once flowed close to Lothal, supporting access by boat.
- Lothal had a warehouse, seals and bead factories linked to long-distance trade.
Commonly credited to
Other archaeologists (e.g. L.S. Leshnik, 1968) argued the basin was a water tank or reservoir for irrigation and drinking; Egypt's harbour at Wadi al-Jarf (c. 2500 BCE) is also a candidate for the oldest harbour.
Evidence for the other claim
- Critics note the inlet's size and position, and that Lothal was a small town.
- Egyptian harbour works on the Red Sea are of similar or earlier date.
What historians and scientists say
Many scholars accept Lothal's basin as a dock, but a minority still read it as a tank, and the 'world's first' label depends on how harbours elsewhere are counted. The question is not fully settled.
