Mằng Lăng Church stands on a gentle hill in An Thạch commune, Tuy An district, 35km north of Tuy Hòa near the Kỳ Lộ river, and holds a specific place in Vietnamese history that goes well beyond its architecture.
How the Church Got Its Name
The area was once a forest of white bằng lăng trees (crape myrtle) - known locally as 'mằng lăng' - and when Father Joseph de La Cassagne (known locally as Cố Xuân), the parish's first priest, cleared the land to build the church starting in 1892, it took the forest's name. One large mằng lăng tree was deliberately spared and later cut into four wooden tables, each 1.7m in diameter, distributed to Làng Sông Seminary, Mằng Lăng itself (kept today in the guest house), Quy Nhơn Cathedral, and Hộ Diêm Church.
Vietnam's Oldest Active Catholic Church
Construction finished roughly 15 years later, making Mằng Lăng the oldest Catholic church still in active use in Vietnam - a red-brick Gothic structure painted blue-grey, with bamboo-shoot-shaped windows, pointed arches, a symmetrical twin-bell tower facade topped by a cross, and moss-covered walls that add to its aged character; the nave seats several hundred across a 5,000 square-metre site. The surrounding grounds are shaded by old trees, the air is quiet, and the congregation is local and devout.
The 1651 Catechism
Two things draw historians and curious travellers here beyond the building itself. First, the church houses the original 1651 edition of 'Phép Giảng Tám Ngày' (Catechism in Eight Days), printed in Rome and written by the Jesuit missionary Alexandre de Rhodes (known in Vietnamese as Đắc Lộ, 1593-1660) - a book widely credited as the foundational text that standardized chữ Quốc ngữ, the romanized script Vietnamese is written in today.
Blessed Andrew of Phú Yên
Second, Mằng Lăng is the birthplace of Chân Phước Anrê Phú Yên - Blessed Andrew of Phú Yên - one of the first Vietnamese Catholic martyrs, executed in Quảng Nam in July 1644 at just 19 years old while evangelizing, and now recognised among 117 martyrs worldwide honoured as 'Blessed' by the Catholic Church. He's venerated today as a patron of Vietnamese Catholic youth, and the church remains an active pilgrimage site around his commemoration and an annual mass for Vietnamese Catholic youth. Mằng Lăng is a quiet, unhurried place that rewards visitors who know what they are looking at.
