Wat Phra That Doi Tung

Was constructed in the 10th century and was renovated by Chiang Rai's most famous ruler King Mengrai during the 13th century and by the famous Chiang Mai monk, Khru Ba Siwichai, at the turn of the 20th century.

The temple complex is comprised of twin Lanna style chedis, one of which is said to contain the left collarbone of the Lord Buddha. Throughout the year, the holy relic draws devout Buddhists from all over Thailand, Laos and Myanmar.

The King Mengrai the Great Memorial

It is located in the town on the intersection leading to Mae Chan. Originally, King Mengrai was the ruler of Nakhon Hiran Ngoen Yang (an ancient town on the bank of the Mae Khong around Chiang Saen) before Chiang Rai was established as the administrative centre in 1262. He consolidated his power by merging the different city in the North and founded the Lanna Thai Kingdom in 1296 with Chiang Mai as the capital.
