A Yakka chieftain named
Saman (who is now regarded as a deity) attained
Sotāpanna (Sovan) after listening to the Buddha's discourse, and asked for a token from the Buddha that they could worship in his absence. The Buddha had given him a handful of hair from his head, which Saman later enshrined in a small
stupa, in height. This was the first stupa to be built in Sri Lanka. According to the Mahawansa, King Devanampiyatissa caused his brother Moolabhaya to deposit the relic of Griwah-Dawtoe (a neck bone) and enlarge it to a height of 30 Cubits. Several kings have since renovated and enlarged this stupa, including
Dutthagamani who raised it to a height of . Other rulers such as
Voharika Tissa,
Sena II,
Vijayabahu I and
Kirti Sri Rajasinha have carried out repairs and maintenance work at the temple. In 1942, a society was formed for the renovation of the temple under
D. S. Senanayake. Reconstruction work began in 1953 and ended in 1980 with the completion of a new pinnacle for the stupa. ==Images==
