Located between Kumana & Lahugala-Kithulana National parks this ancient Buddhist monastery is also believed to be the place where according to preserved Vedda legend for us a recollection of a lost race known as the Nittevo. There has been much controversy as to the identity of this folk. Some hold that the Nittevo are a lost tribe of Negritoes while others believe them to have been some kind of ape-man. Yet others identify them with an extinct species of bear known as rahu valaha.

The Nittevo are said to have been a dwarfish race of men who lived in the Mahalenama region now within the Yala East Intermediate Zone and the Tamankaduva area. These folk are believed to have been exterminated by the Veddas about 250 years ago.
