Archaeological excavations conducted by the Archaeological Survey of India (ASI) beginning in 2014, and later by the Tamil Nadu State Department of Archaeology (TNSDA), have revealed the remains of a large, well-organized settlement associated with the Sangam period. Radiocarbon dating of organic samples recovered from excavation layers indicates that the settlement dates to at least the 6th century BCE, providing important evidence for early urbanization in the Vaigai River valley.[1]
Excavations at Keezhadi have uncovered structural remains including brick-built buildings, drainage systems, industrial installations, and habitation features, indicating a planned urban settlement. Artefacts recovered from the site include pottery, terracotta figurines, iron tools, ornaments made of shell and semi-precious stones, ivory objects, spindle whorls, and punch-marked coins. Pottery fragments bearing Tamil-Brahmi inscriptions have also been discovered, providing evidence of literacy and written communication among the inhabitants.
The Keezhadi excavations form part of a broader archaeological survey of the Vaigai river basin, during which over 293 archaeological sites were identified, indicating the presence of an extensive network of early historic settlements in the region. These findings have contributed significantly to the understanding of early Tamil society, including its urban planning, craft production, trade networks, and social organization.
Scholarly discussion continues regarding the precise chronological relationship between Tamil-Brahmi inscriptions and the earliest radiocarbon-dated occupation layers at Keezhadi. Some researchers have noted that further stratigraphic and chronological analysis is required to establish definitive correlations between inscribed artefacts and the earliest phases of occupation.[2]
The Keezhadi Heritage Museum, inaugurated on 5 March 2023 near the excavation site, displays artefacts recovered from Keezhadi and nearby sites, including pottery, tools, terracotta figurines, ornaments, and burial artefacts. The museum provides an important public resource for the interpretation and preservation of the archaeological discoveries from the Vaigai river valley.[3][4]
Keezhadi is regarded as one of the most important archaeological sites in South India, providing key evidence for early urban settlement, literacy, and cultural development in ancient Tamilakam.
Excavations
An archaeological survey team under Archaeologist Amarnath Ramakrishna [5] was first conducted in 2013 in the vicinity of the Vaigai river from Theni district to Ramanathapuram district where the river meets the sea.[6] During the study, 293 sites, including Keezhadi, were identified to have archaeological residues.[7] The first three phases of excavation at Keezhadi were conducted by the Archaeological Survey of India, and they dropped it from doing further research. A public interest litigation was filed and following that the court ordered the regional depart to carry forward, following which the fourth and fifth phases were conducted by the Tamil Nadu Archaeology Department.
Radiocarbon dating
Radiocarbon dating of organic materials recovered from excavation layers at Keezhadi has provided important chronological evidence for the antiquity of the settlement. Samples including charcoal, carbonized seeds, and other organic remains were analyzed using accelerator mass spectrometry (AMS) radiocarbon dating techniques. Results obtained from laboratories such as Beta Analytic in the United States indicated dates extending to approximately the 6th century BCE, suggesting that the settlement was occupied during the Early Historic period.[8]
These radiocarbon dates provide a scientific basis for establishing the chronological framework of the Keezhadi site and indicate continuity between Iron Age cultural phases and early urban settlement in the Vaigai River valley. The results have contributed to understanding the emergence of early historic urbanization and complex societies in ancient Tamilakam. However, scholars have noted the importance of correlating radiocarbon dates with stratigraphic context and associated artefacts, including inscribed pottery, to establish precise cultural and chronological associations.[9]
Carbon nanomaterials in Keezhadi pottery
Scientific analysis of pottery fragments excavated at Keezhadi has identified the presence of carbon nanomaterials, including single-walled and multi-walled carbon nanotubes, in the black coatings applied to the inner surfaces of ceramic vessels.[10]
The nanostructures were detected using high-resolution transmission electron microscopy (HRTEM), Raman spectroscopy, and X-ray diffraction analysis. Researchers observed that these nanomaterials were embedded within the carbonaceous coating applied to the pottery, likely as part of a surface treatment intended to improve durability, impermeability, or functional performance of the vessels.
The presence of carbon nanotubes in ancient pottery suggests that artisans at Keezhadi employed advanced ceramic processing techniques involving high-temperature firing and carbon-rich materials. Although the formation of these nanostructures was likely an unintended by-product of traditional manufacturing methods rather than deliberate nanotechnology, the findings demonstrate a high level of technological sophistication in ceramic production during the early historic period.
These discoveries contribute to the broader understanding of technological development in ancient Tamilakam and provide evidence for complex material processing techniques used by early historic societies in South India.[11]
