Three Kings Monument Cultural Arts Centre, Chiang Mai Thailand
The importance of the three Kings to the Thai people can be summarised as follows: King Mengrai founded the Lanna Kingdom and established Chiang Mai as the capital. King Ramkamhaeng was responsibly for creating the Thai alphabet and for establishing Theravada Buddhism as the state religion of Thailand. King Ngam Muang was the King of Phayao, a province in northern Thailand. According to legend, Mangrai first made peace between King Ngam Muang of Phayao and King Ram Khamhaeng of Sukhothai in the year 1287 after one King seduced the others Queen. The three Kings then made a pact of strong friendship which endured over the years.
The monument acts as a meeting point for many local people as well as a shrine, with many Thai people leaving offerings at the foot of the statues.
