The Ambalama (Sinhala: අම්බලම) is a simple structure that was designed to provide shelter for passing travellers. There were no charges for using the premises of the Ambalama as it was made, as an offering of goodwill (Pinkama). Ambalamas were also ideal points where it is said, many a traveller would recite old Sinhala poetry for the others sharing the night's rest. This structure was of indigenous architecture and made to withstand weather conditions. 

The Kossinna Ambalama is located in the small town of Kossinna between Kadawatha and Ganemulla in the Gampaha District. This Ambalama depicts no artwork but sits in the middle of a paddy field truly beautiful location.
