Keeladi and the Sangam Age

A short drive south-east of Madurai, past the town of Silaiman, the land flattens into coconut groves along the Vaigai river. There is little to warn you that beneath a low mound here archaeologists have spent the better part of a decade uncovering an ancient Tamil town — brick walls, wells, workshops and, most talked about of all, pottery scratched with some of the earliest Tamil writing yet found. This is Keeladi (also spelled Keezhadi), and the finds have reshaped how the Sangam age is discussed. They have also stirred a debate that is still unresolved, so it is worth separating what the trenches have shown from what is still argued over.

A mound on the Vaigai

Excavations began in 2015, when the Archaeological Survey of India (ASI), under superintending archaeologist K. Amarnath Ramakrishna, opened the first trenches. From 2017 onwards the Tamil Nadu State Department of Archaeology took the work forward across successive seasons, and digging has since spread to related sites nearby along the river. What makes Keeladi unusual is that it is not a temple or a fort but the remains of an ordinary settled town — the everyday fabric of Sangam-age life, which is exactly the sort of evidence that rarely survives.

What the digs found

The trenches have yielded brick structures with proper walls and floors, terracotta ring wells, and drains — the signs of a planned, permanent settlement rather than a temporary camp. Alongside them came a great mass of everyday objects: spouted pots and fine black-and-red ware, glass and carnelian beads, gold ornaments, ivory objects and dice, and terracotta figurines. Spindle whorls, dyeing vats and other industrial traces point to weaving and craft production on a scale that suggests trade. Taken together, the finds describe a busy, well-organised town where people made things, traded and kept house.

The single most discussed category is the inscribed pottery. Archaeologists have recovered a large number of potsherds carrying Tamil-Brahmi letters and so-called graffiti marks — short signs scratched onto vessels. A number of the Tamil-Brahmi sherds appear to carry personal names, hinting that reading and writing were not confined to an elite but were part of ordinary commercial life.

A literate, urban Tamil society

This is the claim that gives Keeladi its wider significance. Read together, the brick architecture, the craft evidence and the inscribed pottery are argued to show a literate, urban Tamil society in the far south during the Sangam age — the period celebrated in classical Tamil poetry. For a long time that literature was the main window onto the age, and some doubted how much of it reflected real, settled town life. Keeladi supplies the physical counterpart to the poems: streets, workshops and writing on the ground. Excavators have also pointed to a secular character to the finds, with relatively little overtly religious material among the domestic objects, though how far to press that reading is itself a matter of interpretation.

The dating debate

How old is Keeladi? Here caution matters, because the dating is genuinely contested. Carbon samples from the site were sent for accelerator mass spectrometry dating, and one sample from a depth of about 3.5 metres was reported at roughly 580 BCE. On that basis the cultural deposit has been described as falling between about the 6th century BCE and the 1st century CE. Some interpretations go further: a report by the first excavator was said to push the beginnings of the settlement, and with it the Sangam age, back towards 800 BCE.

These early dates are what fuel the argument. If accepted, they would place a literate, urban Tamil culture close in time to the so-called second urbanisation of the Gangetic plain in the north, rather than long after it — a claim with real weight for how the antiquity of Tamil writing and town life is understood. But radiocarbon dates fix the age of a sample, not necessarily the moment writing or the town began, and the interpretation has been disputed between state archaeologists and the ASI, which has sought revisions to reports. The debate has also become politically charged, tangled up with questions of Tamil identity. The honest position, for now, is that Keeladi shows an important early historic town whose earliest dates and their wider meaning remain under review — not a settled record, and certainly not proof of the ‘oldest’ anything.

Seeing Keeladi today

You can visit both the ground and the finds. The excavation area itself lies among the groves near Silaiman, with roofed trenches and interpretive boards; the digs are active, so what is open varies by season. The richest experience is the Keeladi (Keezhadi) Heritage Museum, purpose-built near the site, where the beads, pottery, inscribed sherds and other artefacts are displayed with context. The Keezhadi excavation site and the museum together make an easy half-day out from Madurai, and they pair naturally with the city itself: the great Meenakshi Amman Temple, the Jain beds and rock-cut carvings of Samanar Hills, and the Gandhi Memorial Museum in the old palace grounds.
