Kosgaha Ulpotha Natabun Viharaya

Dimbulagala Rock is known to the public for the Dimbulagala Rajamaha Viharaya . However, Dimbulagala Rock is dotted with ancient ruins that many people are not aware of. Kosgaha Ulpotha is one such site hidden in the dense forest on the eastern slopes of Dimbulagala Rock.

Dimbulagala Rock was until recently home to a community of Veddas, who are believed to be descendants of the original aborigines of Sri Lanka who have maintained their original hunter-gatherer lifestyle for millennia.

There were 4 small Vedda settlements around Dimbulagala Rock, which was called Gunners' Quoin. These settlements are Ulpota , Kohombolewa , Alagonagoda and Gonandamene, of which Ulpota was considered the most important of the group. All these settlements consisted of a few huts in the early 20th century, eight in Kohombolewa and three in Gonandamene .
