Poson Poya (Mid June - On Poya Day (Full Moon))
The annual Poson festival is an ancient celebration which commemorates the introduction of Buddhism to Sri Lanka in the third century BC. It was spread by the arrival of Arahat Maha Mahinda (son of King Asoka of India) who appeared before the Sri Lankan King at Mihintale. This religious day is celebrated with the lighting of lanterns (similar to vesak) and pandols depicting the journey.
