The artifacts unearthed in Anuradhapura, Tissamaharama, Mantottam (Mantai and Mannar) and Kantarodai in Sri Lanka confirm that these areas had been with ancient human settlements and important urbanized sites from the beginning of the proto-historic period. Accordingly in Kantarodai, on a plot of land of an area of 2 square km. located at a height of 28- 30 feet above mean sea level, soil strata with archaeological evidence discovered to evince that ancient human settlements had been in existence in the past. This region surrounded by a naturally fertile soil strata with the water resources of Walukkaiyaru linking Kantarodai were sufficient reasons to believe for the occurrence of these ancient settlements. People have lived in these regions since proto-historic period.
Further, ancient harbours around the Jaffna Peninsula such as Jambukolapattna (Kankesanturai), Kayts (Sukaratittha or Uratota) and Mantai (Mantottam) had opportunities to have trade and cultural links with countries such as China, India, and Rome, found at Kantarodai. The pillar inscription found at Kantarodai provides information about the alms offered to the Buddhist temple in the vicinity by King 4th Dhappula who ruled the country from Anuradhapura, the capital. A Sinhala literary text titled ‘Nampota’ belonging to the Kandyan period refers to the North of Sri Lanka as Tamil Paddanam (Damela Paddina) and Kantarodai as one of the places where Buddhist temples such as Kadurugoda Viharaya were situated.
According to a historic legend, Buddha resolved a throne dispute between two Naga kings named ‘Culodara and Mahodara in Nagadipa and stayed in retreat for some time. Sixty monks who lived in Puvanativu (Punkudutivu) attained the ‘Arahantship’ and died after consuming poisoned food and their ashes were buried in this placeaaworld to reveal the historic antiquities of the region. Subsequently Sri Lankan Department of Archaeology conducted an excavationon archaeological research in 1966 in Kantarodai and discovered 57 small and medium sized Buddhist Stupas. Architectural skills could be recognized in these stupas and these stupas have been conserved with coral and lime stones for preservation. Architectural features of a stupaghara could be seen among the stupas as well.
Artifacts related to ancient settlements, statues, parts of buildings of stupas ect and archaeological evidence have been displayed in Jaffna Archeological Museum. Hence, this region assumed to be a place of human concentration in the ancient times, has been declared to be recognized as an archaeological reserve.
