Lanka Patuna is located 40 kilometers away from Mutur town on the Eachchilapmattai – Batticaloa coastal belt in Verugal Division. One of the oldest Buddhist temples “Samudragiri Viharaya” is located here by the beach on fifteen acres of land. It is believed that the Indian Prince Dhantha and Princes Hemamala landed here in the 4th century CE carrying the sacred tooth relic of the Buddha from Kalinga in India. The relic was under threat, therefore sent to Lanka, which was the abode of Buddhism.
Lanka Patuna vihara is gifted with the beauty of nature as its eastern boundary is the ocean and southern boundary is the lagoon. The ruins of the ancient Buddhist temple can be found scattered in a large area and a new dagoba has been constructed. The Vihara provides boarding facilities for devotees.
At the same time it was earlier called as Ilankaithurai Mugaththuwaram. It has a very beautiful blue water beach with corals (like Hikkaduwa beach in the South of Sri Lanka). It has to be rehabilitated.
