Dedigama Kota Vehera, also know as Suthigara Chethiya, was built by King Parakramabahu the Great ( 1153-1186). It is situated in the village of Dedigama in Kegalle District, Sabaragamuwa province. The Stupa can be reached by travelling along the Nelundeniya - Galapitamada road (B540). The site is just 4 km from the Nelundeniya junction. It was discovered that the Stupa is built on top of another smaller stupa. Both stupas were built around the same time; the smaller Stupa is constructed in the exact location where King Parakramabahu was born. 

The Stupa was discovered during British rule by F.M. Price, the Government Agent in the Kegalle area (Wikramasinghe, 1990). The diameter of the lager Stupa is 256 feet and 47 feet in height. The top of the Stupa is approx 26,000 square feet flat surface.
