General Studies Paper I: Indian Heritage and Culture (Archaeology and Ancient History)
- Reported in The Hindu (13 Oct 2025), it’s part of TNSDA’s ongoing archaeological “revolution”.
Context & Significance – Tamil Nadu’s Archaeological Revolution
- Tamil Nadu is challenging historic timelines with state-funded excavations at 8+ sites since 2024.
- Recent carbon dating (Keezhadi, Mayiladumparai) pushed back Iron Age and Sangam era origins by centuries.
- Government allocated ₹5 crore for expanded excavations, using modern techniques and partnerships with ASI.
- Emphasizes Megalithic–Iron Age burials, shifting focus from North to South India.
Why Thirumalapuram is Important
- Located near the Western Ghats, bridging highland–lowland settlement history.
- Found rare urn burials in stone slab chambers, indicating advanced funerary systems.
- Anticipated to be among the earliest Iron Age sites in India (early to mid third millennium BCE).
- May link Tamil metallurgy and high-tin bronze to Southeast Asian trade networks.
Details of Excavation – Location
- Thirumalapuram covers ~35 acres in Tenkasi district, northwest of village, near seasonal streams and Kulasekaraperi tank.
- Excavation started in 2025 with 37 trenches, led by TNSDA.
