Saint Anna Nong Saeng Catholic church

Saint Anna Nong Saeng Catholic Church stands at the far north end of Nakhon Phanom town, on the riverside road facing the Mekong, its parish dating to 1926 when Vietnamese Catholic immigrants settled in the city. The building visitors see today is newer: a replacement chapel completed and opened in 1975, built with twin towers and steeples connected by a high footbridge — a silhouette that echoes Bangkok’s Assumption Cathedral from the same architectural period. It holds co-cathedral status within the Metropolitan Archdiocese of Thare and Nonseng. Entry is free and the church is open daily 08:00–16:30.

The Vietnamese influence in the design sets it apart from most churches in Thailand — the twin-tower, linked-steeple layout isn’t the European Gothic-revival template found elsewhere, but a distinct regional variant tied to the community that built it. Inside, the sanctuary is simply furnished with wooden pews and a modest altar; the exterior and the riverside setting are the main draw rather than elaborate interior decoration. Next to the chapel stands an older building, put up in 1952, that has the look of a colonial-era rectory even though it postdates the colonial period — a detail that surprises visitors expecting the newer chapel to be the oldest structure on site. The compound is large, with a clear view across to the Mekong.

Nakhon Phanom’s population has long included Vietnamese, Chinese, and Lao communities alongside Thai, and this church functions as a visible marker of that mix in a province where Buddhist temples dominate the skyline. It remains an active parish — expect quiet reverence during services, and time a visit outside Sunday morning if you want to look around without interrupting worship.

Insider Tip: Combine the visit with a walk or cycle along the Mekong promenade right outside — the river view and the church’s twin towers make a good pairing, especially near sunset.

Dress modestly — shoulders and knees covered — as you would at any religious site in Thailand. For another example of the region’s Catholic heritage, Saint Joseph Ban Kham Koem Church is elsewhere in the province, and the Nakhon Phanom destination guide covers the rest of the riverside city.
