According to the Nakhon Si Thammarat’s chronicle, the main stupa of the temple, called Phra Borommathat Chedi, literally, the Great Noble Relics Stupa, was built prior to other religious architectural buildings in the temple by King Sri Dhammasokaraja in approximately the early 13th century CE. in order to establish the Theravada Buddhist symbol on the land and to serve the belief of his people on the presence of the Buddha’s relics in situ which should be housed by the stupa. Other literary sources provide a reasonable assumption that after the misery of an epidemic which was sweeping through the town, people scattered and the town was almost deserted. The king’s project of building the stupa for housing the relics was created as a mean of encouraging greater participation by his subjects. Thus the stupa caused the coming back to rebuild and develop the town community which was united in its support for constructing and maintaining the stupa and the temple as the main spiritual centre for the people. Other religious architectural buildings in the compound had been built from the early 13th century to the 18th century CE. including Wihan Bodhi-Lanka, the roofed cloister round the Bodhi Tree which is believed to be a sprout of the Bodh Gaya’ s Bodhi Tree under which the Buddha reached Enlightenment.
