Designed in the early Gothic style, it would not look out of place as a modest parish church in England.
However, set on the edge of Merdeka Square, and flanked by traffic-clogged highways, St Mary's looks somewhat incongruous these days.
The architecture may not set any pulses racing, but it does have a certain nostalgic charm, an echo of a world gone by. If all this sounds a bit sad, St Mary's has a thriving multi-cultural congregation, as befits the seat of the Bishop of West Malaysia.
Sunday sees separate services in English, Iban, Nepali and Bahasa Melayu, a sign of how disparate the flock now is.
