The Gampaha heritage zone located in the western province of Sri Lanka has evidence that runs back to the pre-historic age. Although Gampaha district has the largest population now archaeological research has identified many stone caves where the pre-historic humans lived. Research done in such places as Varana, Pilikuttuwa and Alawala has confirmed human activities since 10,000 years from today. After the proto-historic period, cemeteries of the pre-historic period (Iron Age), cave temples with inscriptions in pre-Brahmi characters representing the historic age, and architectural constructions representing the colonial era are scattered throughout the zone.
The Central Cultural Fund began heritage management in the zone in 2015 and architectural conservation and mural conservation are now in progress.
