Lankarama stupa was constructed by King Valagamba in an ancient place at Galhebakada in the early kingdom of Anuradhapura, Sri Lanka. Nothing is known about the old form of the stupa, and later this was renovated. The ruins show rows of stone pillars, and it is no doubt that a house has been built encircling the stupa vatadage to embrace it. The round courtyard of the stupa seems to be three over the area. The diameter of the stupa is 14 m. The yard is round in form, and the diameter is 406 m.
