Where Ancient Heritage Meets Progress
Gampaha District, carved from Colombo District on September 7, 1978, is Sri Lanka's most populous district with over 2.4 million residents. Located in the Western Province, it serves as the nation's economic engine — home to the Katunayake and Biyagama Export Processing Zones, employing nearly 60,000 workers and generating billions in export revenue.
From the sacred grounds of Kelaniya Raja Maha Viharaya — where Buddha himself visited in the 3rd century BCE — to the modern industrial corridors driving Sri Lanka's apparel and electronics exports, Gampaha is a district of remarkable contrasts and boundless potential.
