It houses the original 'Cathechismus' book, which played a foundational role in the transition from Chinese characters to the modern Latin-based Vietnamese alphabet.
The church was named after a type of local plant, 'Mang Lang', which once grew abundantly in the surrounding area.
The building features distinctive blue-gray stone paint that has weathered to create a unique historical patina.
The architect was Father Joseph Lacroix, a French priest who incorporated European structural elements into the rural Vietnamese setting.
Mang Lang Church is one of the oldest Catholic churches in Vietnam, originally constructed in 1892 in the Tuy An district of Phú Yên province. The structure is built in a classic Gothic architectural style featuring symmetrical bell towers and a central vaulted entrance. It serves as the repository for the first book ever printed in the Vietnamese national language using Romanized script (Chữ Quốc Ngữ). The book, 'Cathechismus', was authored by Alexandre de Rhodes and published in Rome in 1651. The site is surrounded by a rural landscape of rice paddies and traditional village architecture. It remains an active parish church serving the local Catholic community. The church grounds contain an underground room used to preserve the historical artifacts related to the development of the Vietnamese script.
