Wat Chanthaburi

Wat Chanthaburi sits on the Pa Sak River in Mueang Kao (“old city”) subdistrict, Sao Hai district — part of Saraburi province, not the eastern seaboard province of the same name. Entry is free and the temple is open daily, 08:30-16:30. The name is a giveaway of the area’s history rather than its geography: it comes from Chanthaburi Si Sattanakhon, an old name for Vientiane, after Lao Wiang communities migrated here and settled along the river during the late Ayutthaya period.

The reason to seek this temple out is the mural work inside its old ordination hall. Painted in the ornate decorative style favoured during the reign of Rama III, the murals don’t stick to standard scenes from the Buddha’s life — they depict the everyday life of the Tai Yuan community that settled here, giving them real value as a historical record alongside their religious content. The stucco-decorated exterior and elaborately carved gable board of the ubosot are typical of temple architecture from that period, and the building stands as a preserved piece of Sao Hai’s Lao-Thai heritage rather than a modern reconstruction.

Insider Tip: The murals are the whole reason to detour here — if the ordination hall is locked when you arrive, ask at the temple office rather than giving up; caretakers will often open it for visitors who ask.

Watch out: don’t confuse this temple in searches or route-planning with Chanthaburi province in eastern Thailand, roughly 300 km away — the shared name is coincidental (both reference old place names), and mapping apps occasionally surface the wrong region.

Sao Hai district holds a cluster of similar Tai Yuan-heritage sites, including Wat Pha Yao and the Weaving Centre of Tambon Ban Ton Tan, which showcases the same community’s traditional cotton weaving — worth combining into a half-day loop rather than visiting Wat Chanthaburi alone. Dress modestly, remove shoes before entering the ubosot, and reach the temple by car or motorbike from Sao Hai or Saraburi town — there’s no direct public transport link.
