Kulakkottan was an early Chola king and descendant of Manu Needhi Cholan who was mentioned in chronicles such as the Yalpana Vaipava Malai and stone inscriptions like Konesar Kalvettu. His name Kulakkottan means Builder of tank and temple. He was son of Vararamatevan who said to have been ruler of Chola Nadu and Madurai. The historian Rasanayagam states that Vararamatevan and Kulakkottan arrived in Trincomalee during the reign of king Pandu of Anuradhapura. Vararamatevan found the Koneswaram temple destroyed by the buddhist king Mahasena and decided to restore it, which was later continued by his son. Kulakkottan was credited for restoring of the ruined Koneswaram temple and tank at Trincomalee in 438, the Munneswaram temple of the west coast, and as the royal who settled ancient Vanniyars in the east of the island Eelam.
