Wat Pho Chai, formerly known as "Wat Phi Phiu," is a third-class royal monastery of the Mahanikaya sect with a profound history dating back to the Lan Xang Era. The temple's paramount significance lies in housing "Luang Pho Phra Sai," a magnificent solid gold-colored bronze Buddha image in the Maravijaya posture. According to historical chronicles, the three daughters of King Setthathirath of the Lan Xang Kingdom commissioned the casting of three Buddha images named after them: Phra Suk, Phra Soem, and Phra Sai. These sacred images were originally enshrined in Vientiane until the reign of King Rama III of the Rattanakosin Kingdom, when they were relocated across the Mekong River to the Thai side.

The relocation process is steeped in both historical record and legendary accounts. During the crossing, a fierce storm caused "Phra Suk" to sink into the Mekong River at the mouth of the Ngum River, where it remains to this day. "Phra Soem" and "Phra Sai" successfully reached Nong Khai. While both were intended for Bangkok, the cart carrying Luang Pho Phra Sai reportedly broke down upon reaching Wat Pho Chai. Despite numerous attempts to repair the cart or replace it, the image remained immovable. Following a traditional ritual of divination, it was decided that Luang Pho Phra Sai wished to remain there, and the image has been enshrined at Wat Pho Chai ever since. Meanwhile, Phra Soem was later moved to Wat Pathum Wanaram in Bangkok.

The interior of the temple's ordination hall features exquisite murals that vividly detail the life of the Buddha and the historical journey of Luang Pho Phra Sai across the Mekong. These artistic depictions serve as a testament to the shared spiritual heritage and deep-seated faith of the people on both sides of the river. Wat Pho Chai stands not only as a site for religious ceremonies but as a cultural pillar and a symbol of the enduring bond between Thailand and Laos. This devotion culminates annually during the Songkran Festival, when the sacred image is traditionally paraded through the streets for a ceremonial bathing ritual, drawing thousands of pilgrims from across the region.
