Buddhism continued to be promoted by King Pha Yu (r. 1345–1367), who shifted the capital to Chiang Mai and built Wat Li Chiang. His successor, Keu Na (1367–1385), invited the forest monk Somdet Phra Mahasami to Lan Na to introduce his Sri Lankan forest sect. Mahasami arrived with some relics which were enshrined at the newly built Wat Suan Dauk. This wat became the headquarters of the Sri Lankan forest sect. Wat Phra Singh (c. 1385) is another example of classic Buddhist architecture of the Lan Na kingdom.
