Phra Maha Chedi Phumiphol

Phra Maha That Naphamethinidon and Phra Maha That Naphaphonphumisiri are located at kilometer marker 41.5 on the left side. They were built by the Royal Thai Air Force in collaboration with the Thai people. Phra Maha That Naphamethinidon was constructed to honor King Bhumibol Adulyadej on the occasion of his 5th cycle birthday anniversary in 1987, and Phra Maha That Naphaphonphumisiri was built to honor Queen Sirikit on the occasion of her 5th cycle birthday anniversary in 1992. Both of these stupas have a similar shape, with a 12-sided base and two levels of glass balconies surrounding them. The top spire houses relics of the Buddha and worship statues. The surrounding area offers beautiful views of Doi Inthanon.
