Kandarodai

Kandarodai (, , also known as ) is a small hamlet and archaeological site of Chunnakam town, a suburb in Jaffna District, Sri Lanka.
Known as "Kadiramalai" in the ancient period, the area served as a famous emporium city and capital of Tamil kingdoms in the Jaffna peninsula of North Eastern Ceylon from classical antiquity. The notable ancient Buddhist monastery referred as Kadurugoda Vihara is situated in Kandarodai.
Located near a world-famous port at that time, Kandarodai was the first site the Archaeology Department in Sri Lanka excavated in the Jaffna peninsula.
Etymology.
According to Jaffna tradition was this place initially known as "Kadiramalai". According to C. Rasanayagam is the Sinhalese name" Kadurugoḍa" derived from "Kadiragoda", which is according to him derived from Kadiramalai, substituting the Tamil suffix "malai" (meaning "mountain") with the Sinhalese suffix "goḍa." The prefix "Kadira" is the Tamil name for the Acacia chundra tree. The modern Tamil name "Kantarōṭai "is believed to be re-derived from the Kadiragoda term. The Tamil name was Kadiramalai.
Some scholars holds that Kadurugoda is derived from the Sinhalese name "Kandavurugoda" (a site of a military encampment). The Portuguese archives refer to this place as "Kandarcudde". The name Kadurogoda viharaya is mentioned in the 15th century Sinhalese text "Nampota".
History.
In 1970, the University of Pennsylvania museum team excavated a ceramic sequence remarkably similar to that of Arikamedu in Tamil Nadu, with a Pre-rouletted ware period, subdivided into an earlier "Megalithic", a later "Pre-rouletted ware phase," followed by a "Rouletted ware period". Tentatively assigned to the fourth century BCE, radio carbon dating later confirmed an outer date of the ceramics and Megalithic cultural commencement in Kandarodai to 1300 BCE. During this excavation, the university team discovered a potsherd carrying a Sinhalese Prakrit inscription written in Brahmi scripts. 
Further excavations were conducted at the site by the University of Jaffna.
Black and red ware Kanterodai potsherd with Tamil Brahmiscripts from 300 BCE excavated with Roman coins, early Pandyan coins, early Chera Dynasty coins from the emporium Karur punch-marked with images of the Hindu Goddess Lakshmi from 500 BCE, punch-marked coins called "Puranas" from 6th-5th century BCE India, and copper kohl sticks similar to those used by the Egyptians found in Uchhapannai, Kandarodai indicate active transoceanic maritime trade between ancient Jaffna Tamils and other continental kingdoms in the prehistoric period.
The parallel third century BCE discoveries of Manthai, Anaikoddai and Vallipuram detail the arrival of a megalithic culture in Jaffna long before the Buddhist-Christian era and the emergence of rudimentary settlements that continued into early historic times marked by urbanization. Some scholars have identified "Kourola" mentioned by 2nd century AD Greek geographer Ptolemy and "Kamara" mentioned by the 1st century AD Periplus of the Erythraean Sea as being "Kadiramalai".
The earliest people of Jaffna were belonging to a megalithic culture akin to the South Indian megalithic culture. The period of Buddhism in the Jaffna Peninsula differ from the rest of the island, which is seen as an overlapping of the megalithic beliefs with Buddhism. According to scholars was Kantarodai, known in Tamil literature as "Kadiramalai", the capital of the ancient Tamil Kingdom ruled by Tamil speaking Naga kings from 7th century AD to 10th century AD. The "Yalpana Vaipava Malai" also describes Kadiramalai as the seat of "Ukkirasinghan" who fell in love with a Chola princess in the ancient period. The ancient Kadurugoda Vihara Buddhist monastery is situated at this site where a 10th century pillar inscription of Sinhalese language recording a regal proclamation of the bequest of gifts and benefits to a Buddhist place of worship was found. Kandarodai was a Buddhist mercantile centre among Tamils.
The domes were reconstructed atop the flat bases of the ruins by the Archaeology Department. The similarities between the finds of ancient Jaffna and Tamil Nadu are indicators of a continuous cultural exchange between the two regions from classical antiquity. These structures built over burials demonstrate the integration of Buddhism with Megalithism, a hallmark of Tamil Buddhism. Outside Andhra Pradesh in India, Kanterodai is perhaps the only site where such burials are seen.
Education.
Kandarodai has a number of education institutions notably Kantharodai Tamil Kandaiya Vidyasalai and Skandavarodaya College.
