Hor Trai Wat Sra Trinurak

Hor Trai Wat Sra Trinurak is a raised wooden scripture library at Wat Sra Trinurak in Ban Na Wiang, Sai Mun district — about 25 km from Yasothon town. Built more than a century ago to keep Buddhist palm-leaf manuscripts safe from insects and flooding, it was surveyed and registered as a national historic monument by the Fine Arts Department in 1990. Entry is free.

The building is a rectangular timber structure roughly 8.3 by 10.5 metres, raised on 30 round wooden columns and facing east — standard practice for a hor trai, since lifting the library off the ground protected the manuscripts stored inside from termites, damp, and the seasonal flooding that affects low-lying Isan rice country. A tiered three-level roof with carved gable finials and swan-tail decoration tops the structure, covered in flat tile shingles that show the Tai Yai and Lao craftsmanship common to old scripture halls in this part of Isan. The proportions are modest next to the region’s larger ordination halls, but the carving detail on the gables rewards a slow look.

Today the hor trai works as a small history museum rather than an active working library — the original manuscripts and religious artifacts are displayed inside, viewable from the surrounding platform. There’s no resident monk stationed at the building itself, though Wat Sra Trinurak functions as a normal working temple around it, so morning almsgiving and occasional chanting still happen elsewhere on the grounds.

Insider Tip: Visit on a weekday morning — weekend visitors are mostly Thai day-trippers combining it with other Sai Mun district temples, and the site gets quiet again by early afternoon.

The temple compound itself is unhurried and rural: shade trees, a village pond nearby, and little passing traffic beyond local motorbikes. There’s no gift shop or food stall at the site, so bring water if you’re combining this with other Sai Mun stops. A small donation toward the temple’s upkeep is appreciated but never asked for.

Getting here means a car or motorbike from Yasothon town — there’s no direct bus route into Ban Na Wiang, so a hired driver or your own transport is the practical option. Dress modestly (covered shoulders and knees) and remove your shoes before stepping onto the raised wooden floor. Combine the visit with Phra That Ku Chan or Phra That Kong Khao Noi elsewhere in Yasothon province for a day focused on the province’s older religious architecture.
