Thuparamaya is a dagoba in Anuradhapura with the base diameter of 18m and 3.45m in height. Thuparamaya, located in the heart of Anuradhapura is considered to be the first dagoba built in Sri Lanka following the introduction of Buddhism. This Chetiya was built in the shape of a heap of paddy enshrining the collarbone of the Buddha. Thuparamaya was destroyed and rebuilt from time to time with the current monument being rebuilt in 1862 AD.
Thuparamaya is surrounded by a granite compound and 2 rows of stone pillars round the dagoba. The stone columns around the dagoba were once supporting a ring shaped roof structure of Thuparamaya.
In 7th century BC, Thuparamaya stupa was rich with gold and silver decorations, bricks and doors. The dagoba was then plundered by the Pandyans (south Indian Tamil), who took away all its gold and treasures. Thuparamaya stupa was later renovated by King Mahinda IV, who re-installed the golden casings and doors. There was another attack on Thuparamaya stupa by Colas (south Indian Tamil), who completely plundered the complex of its valuables.
