During the reign of King Parakumbha VI (1415-1467) the construction of the temple was begun and completed in all aspects with the royal patronage.

King built the temple closer to his royal palace, to doing the necessary duties to the Sangha community.

[3] However most of the constructions and artifacts of the original temple had been destroyed and taken away by the foreigners leaving only a few ruins at the place.

It is said that only some ruins of the present Stupa, parts of Katharagama Devalaya, and some stone pillars were remained in the Vihara premises.

[2] The Kotte Raja Maha Vihara is mentioned in Aththaragama Bandara Rajaguru's book Vihara Asna (Nam Potha), a Kandyan period compiled book about the important Buddhist centers in Sri Lanka.
