Wat Si Pho Chai

A 400-year-old bronze Buddha named Luang Pho Yai sits inside a 16th-century Lan Xang-style chapel at Wat Si Pho Chai, in Ban Saeng Pha village, Na Haeo district — Loei’s mountainous border strip with Laos. Entry is free.

The temple’s founding is tied directly to the village around it. Records place its start in 1547, when a group of hunters led by a man named Siang Pha travelled from a walled settlement and settled here with their families, founding what became Ban Saeng Pha — the subdistrict still carries his name. The temple gained formal status in 1832. That makes Wat Si Pho Chai roughly contemporary with the last century of the Lan Xang kingdom, which once ruled this stretch of the Mekong watershed before Siam and the French colonial border eventually split it from what’s now Laos.

That Lan Xang heritage shows most clearly in the sim, the temple’s ordination hall. Built in the same era as the temple’s founding, its brick-and-stucco form closely resembles Wat Xieng Thong in Luang Prabang — one of Laos’s most celebrated temples — and blends Lan Xang, Ayutthaya, and Chinese decorative elements rather than the Lanna style found in temples further north around Chiang Mai. Inside sits Luang Pho Yai, a bronze Buddha cast in the Lan Xang tradition, seated cross-legged in the diamond meditation posture with hands in the Mara Vijaya gesture — 87 inches across the lap, 133 inches tall, and reckoned at more than 400 years old.

Na Haeo district itself sits high and cool by Loei standards, close enough to the Laos border that the temple’s Lan Xang links feel geographically obvious rather than accidental. Namtok Than Sawan and Phu Suan Sai National Park, both also in Na Haeo district, are the district’s other reasons to make the drive out from Loei town.

Insider Tip: The sim’s resemblance to Wat Xieng Thong is the real draw for anyone who’s already been to Luang Prabang — it’s a rare chance to see closely related Lan Xang temple architecture without crossing the border.

Watch out: Don’t confuse this with Wat Pho Chai in Nong Khai — a much larger, more visited temple with a similar name and its own famous Buddha image, hundreds of kilometres away on the other side of Isan.

Dress modestly, shoulders and knees covered, and remove your shoes before entering the sim. Mountain roads into Na Haeo have tight bends, so allow extra time and expect cooler temperatures than lowland Loei.
