Tissamaharamaya, also known as Mahagama, was discovered by the Prince Mahanaga, brother of the famous King Devanampiyatissa in the 3rd Century BC.
The city of Tissamaharama is documented to have been in its peak during the time of King Kavantissa, where the well-known stupas of Maha Dagoba, Sandagiri Dagoba, Yatala Dagoba and Menik Dagoba and the beautiful man-made reservoirs of Tissa Wewa and Debara Wewa were built.
Tissamaharama Sri Lanka, once a sanctuary from marauding Dravidian invaders from Southern India, is an ideal access point for the nearby Yala National Park, Bundala National Parks and the Katharagama Pilgrimage.
Tissamaharama, which can also be called Tissa is a major cultural and nature attraction although it is visited mainly in view of it being the gateway to the Yala National Park. Tissamaharama is worth touring due to the three ancient stupas and the two irrigation reservoirs as well as the lovely expanses of paddy fields in which the town is bounded from the Northern side. The largest stupa of Tissamaharama, the Sandagiri Dagoba is situated in the middle of the paddy fields.
