Ban Song Yae Catholic Church (The Archangel Michael’s Church)

St Michael’s Church at Ban Song Yae is Thailand’s largest wooden church — 57 metres long, 16 metres wide, raised on roughly 360 hardwood piles — standing in a rural corner of Thai Charoen district in Yasothon province. It’s a genuinely rare building type in a country where Buddhist temples dominate the religious landscape, and it remains an active Roman Catholic parish rather than a preserved relic.

The Catholic community here traces back to 1908, when the first five families settled in what was then called Ban Nong-Song-Yae after being taught the faith by visiting missionary priests. A temporary chapel went up the following year, and by 1919 the congregation had grown to around 400 members. The current church — the fourth built on the site — began construction in 1947 using timber donated by villagers, was completed in 1953, and was consecrated by Bishop Claudius Baye on 25 April 1954. The floor is built from Malabar ironwood and jamba timber, strong enough to support wooden pews seating well over a thousand people. A 1981 renovation replaced the original roofing with corrugated iron, and a 1994 repair project replaced 124 of the building’s 227 support poles after termite damage — an ongoing maintenance reality for a structure this size built almost entirely from wood.

Inside, Catholic iconography sits alongside the Thai-style roofline and timber construction that mark the building as distinctly regional: statues and artwork depicting the Archangel Michael, stained glass letting colour into the nave, and a scale that makes the building feel more like a provincial cathedral than a village chapel. The Tourism Authority of Thailand has featured it under its “Unseen in Thailand” banner, which is roughly how well-known it is outside the local Catholic community — a genuine curiosity rather than a mainstream stop.

Insider Tip: If you want to see the church in active use rather than as an empty building, time your visit for a Sunday morning Mass — hymns are sung in Thai, and the scale of the wooden nave is far more striking with a full congregation than empty.

Watch out: This is a working parish church in a rural district with no public transport connections, so you’ll need your own vehicle, a hired driver, or a tour that includes it. There’s little else in the immediate area to combine it with, so budget it as a dedicated stop rather than a quick add-on.

Dress modestly — covered shoulders and knees — as you would for any active place of worship, and keep voices down if a service or private prayer is underway. The church grounds also include a small museum dedicated to Reverend Desaval, one of the missionary priests credited with founding the parish, worth a look if it’s open during your visit. For contrast, Yasothon’s Buddhist landmark Phra That Kong Khao Noi sits elsewhere in the province and shows the more typical side of the region’s religious architecture.
