- Sembiyankandiyur Neolithic Site — An archaeological site where in early 2006 a polished Neolithic stone celt engraved with four signs resembling the Indus script was discovered by a local schoolteacher. Epigraphist Iravatham Mahadevan saw it as strong evidence that Neolithic Tamil Nadu and the Indus Valley people may have shared a Dravidian language. Later ASI excavations yielded Megalithic/Iron Age pottery, urns and bowls dated between roughly 300 BCE and 100 CE.
