Trace India's maritime heritage from Lothal to Mahabalipuram. How can initiatives like the National Maritime Heritage Complex revive it?

India's seafaring heritage goes back about 4,500 years [1]. It runs from the Harappan port of Lothal to the Pallava harbour of Mahabalipuram, and it linked the subcontinent with West Asia, Southeast Asia and the Mediterranean. Reviving it now serves both cultural and blue-economy goals.

Tracing the heritage: Lothal to Mahabalipuram

• Harappan phase: Lothal in Gujarat had a brick-lined dockyard and bead workshops that traded with West Asia. This is why the NMHC is being built there [1].
• Early historic phase: Ports such as Muziris and Arikamedu traded spices and textiles with Rome. Kalinga sailors reached Southeast Asia, and Odisha's Bali Jatra festival still remembers them.
• Pallava phase: In the 7th century AD, the Pallavas built Mahabalipuram into a port that traded with Southeast Asia and the Mediterranean. A log fire guided ships into harbour [2].
• Continuity: The Cholas later took naval power as far as Srivijaya. In 1887, a lighthouse was placed on the roof of the Olakkaneeswar Temple at Mahabalipuram, joining the ancient port to colonial navigation [2].

How NMHC can revive it

• Showcase: The complex has museum galleries, a replica Lothal township and a naval gallery [1]. Its 77 m lighthouse museum is planned as the world's tallest and its design is inspired by Mahabalipuram, so it links both ends of the story. DGLL is funding it at ₹266.11 crore [2].
• Research: A Maritime Research Institute is being set up with the Indian Maritime University [2].
• Diplomacy: An MoU with Vietnam covers exchange of artefacts, a conservation laboratory and maritime-heritage tourism [3]. This supports the Act East policy.
• Livelihoods: About 22,000 jobs are expected, and Phase 2 will be developed through PPP [1].
• Wider network: The Marine Aids to Navigation Act, 2021 lets the Centre designate heritage lighthouses for cultural and tourism use [4]. Tourist facilities were added at 75 lighthouses for ₹60 crore [5]. Lighthouse visitors rose from 4 lakh (2014) to 18.63 lakh (2024–25) [2].
• Safeguards: Bring in ASI experts for towers that stand on monuments. Keep all building CRZ-compliant. Publish visitor and local-income data for each site before expanding further.

India's maritime story runs unbroken from Lothal's dock to Mahabalipuram's temple-top light. Backed by a network of heritage lighthouses, the NMHC can turn this past into a living asset for education, diplomacy and coastal jobs, as long as conservation and local benefit come first. That would honour the Article 51A(f) duty to preserve our composite heritage and support SDG 14.
