This is the place where the mythical Pulasthi Rishi was said to live and the place of which the mythical King Ravana was born. The temple was built by King Devanampiya Tissa 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 again renovated this viharaya and named it as "Boupulvan, Kasubgiri Radmaha Vehera". 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 belongs 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.

Isurumuni Lovers
6th Century Gupta style carving. The woman, seated on the man's lap, lifts a warning finger, probably as a manifestation of her coyness; but the man carries on regardless. The figures may represent Dutugemunu's son Saliya and the low caste maiden Asokamala whom he loved. It's known that he gave up the throne for her. ‘Siddha mahayaha kuni – maha ka Asala yaha ni’ The above Brahmi inscription was inscribed at the original place where the Isurumuniya Lovers were originally sculptured and placed. It is a special one as a letter in this inscription is 3 inches x 4 inches in size. After donating Vessagiriya to Maha Sangha this sculpture would have been removed and placed at its present place. The Lovers in the sculptured plaque are King Kuvera Vaisrawana and his Queen Kuni. Ramayana states that Vaisrawana who lived in Vessagiriya ruled Sri Lanka from Lankapura before Rawana.
The Royal Family carving is carved on a Granite plate. There are five human figures carved on this plate. The human figure in the center is King Dutugamunu, who has a tall crown on his head and a "puna noola" around his chest. At his left are another two human figures. They are fanning him with a "Wijinipath"
There are four elephants in this carving. It shows them bathing. The elephant figures here are very similar to the elephant figures in "Mamallapuram" In India.
