- Punnaikayal — A historic harbour village at the mouth of the Thamirabarani river, called 'Punicale' by the Portuguese, who made it their principal southern-coast possession for about 50 years from 1551. They built hospitals, a seminary and a mud fort here, and the first Tamil printing press was set up at Punnaikayal in 1579. It succeeded the older port of Kayal in regional maritime trade.
