The Roman Catholic church in Seria is a modest white building on the edge of the oil town's residential area, serving the small but longstanding non-Muslim community that the petroleum industry brought to this corner of Brunei. It is not architecturally remarkable, but it is an interesting counterpoint to Seria's overwhelmingly Malay and Islamic public character — a reminder that this planned company town once housed a genuinely international community.
Regular services are held in English and Filipino. Visitors are welcome outside service hours. The church sits a short walk from the main commercial strip, in the quieter residential section of Seria built for middle-ranking Shell employees. The surrounding streets have the slightly faded air of colonial-era company housing — bungalows and semi-detached houses that have been modified over decades but retain their original proportions.
