Era : Anuradhapura,
Built : King Devanampiya Tissa,
This is the place where Pulasthi Rishi was live and the place of which King Ravana was born. This place has written history of about 5000 years. Further this place is one of 3 star gates in the world. The temple was built by King Devanampiya Tissa (307 BC to 267 BC) who ruled in the ancient Sri Lankan capital of Anuradhapura. After 500 children of high-caste were ordained, Isurumuniya was built for them to reside. King Kasyapa I (473-491 AD) again renovated this viharaya[citation needed] and named it as "Boupulvan, Kasubgiri Radmaha Vehera".[citation needed] This name is derived from names of his 2 daughters and his name. There is a viharaya connected to a cave and above is a cliff. A small stupa is built on it. It can be seen that the constructional work of this stupa belong to the present period. Lower down on both sides of a cleft, in a rock that appears to rise out of a pool, have been carved the figures of elephants. On the rock is carved the figure of a horse. The carving of Isurumuniya lovers on the slab has been brought from another place and placed it there. A few yards away from this vihara is the Ranmasu Uyana.
