Alagankulam is a village situated on the east coast in Ramanathapuram Taluk and district. The village is situated on the banks of the river Vaigai and is about three kilometers away from the seashore.
The most significant findings of the excavation are hundreds of potsherds of the Mediterranean
region. They include Rouletted ware and Amphorae jar pieces. Pieces of Red ware with Tamil Brahmi letters have been found. They are assignable to the first century BCE. Other antiquities include beads, perforated tiles, and bricks in various levels. Three Roman coins were unearthed.
They contain the figure of the head of the Roman Emperor on one side and the figure of
goddess of victory, holding a globe on the other side. The legend on them shows that the Roman Emperor Valentine II who ruled around 375 CE issued the coins.
