Proper documentation of the area begins with the Portuguese, the first European power to seize control of the maritime districts of Sri Lanka. During their administration from 1505 to 1656, t he Portuguese carefully compiled lists of villages so that the task of collecting taxes would be made easier. These lists (thombos) contained not merely names but detailed descriptions of the location and extent of each village as well as of the agricultural produce, including timber and fruit trees, fount there. The antiquity of certain village is made manifest in these Portuguese records for modern towns and villages in the Sinharaja region such as Kalawana and Pothupitiya still bear the same name they had when the Portuguese wrote about them four centuries ago.
