Phra Maha Chedi Chai Mongkhon

Phra Maha Chedi Chai Mongkhon is a large Buddhist chedi located within Wat Pha Nam Yoi in Nong Phok District, Roi Et Province, northeastern Thailand. Standing 101 meters tall and 101 meters wide on a forested hill, it is one of Thailand's largest chedis. Built to enshrine Buddha relics and notable for its ornate golden exterior blending central Thai and Isan styles, it serves as a major pilgrimage and sightseeing landmark in the region.

Visitors can expect a vast golden chedi complex set on a forested hill within Wat Pha Nam Yoi temple grounds. The exterior is elaborately decorated with gold mosaic and surrounded by gardens and smaller shrines. Inside, multiple floors contain Buddha images, relic chambers, murals and museum displays. The upper levels offer panoramic views of the surrounding countryside. The site is spacious, quiet and primarily for sightseeing, photography and merit-making.

The chedi was initiated by Phra Ajarn Si Mahawiro, a disciple of Luang Pu Man Phurithatto, to enshrine Buddha relics and serve as a center for Buddhist practice. Construction began in 1985 with contributions from devotees and was built on Pha Nam Yoi hill, a former forest meditation site. The dimensions of 101 meters in width, length and height symbolize the name of Roi Et province.

The chedi is a significant Buddhist pilgrimage site in Isan, enshrining Buddha relics on its top floor. It reflects Isan and central Thai architectural styles and serves as a center for religious ceremonies, merit-making and meditation within Wat Pha Nam Yoi, also known as Wat Pha Namthip Thep Prasit Vararam.
