Mang Lang Church

Mang Lang Church is a historic Catholic church located in An Thach Commune, Tuy An District, about 35 km north of Tuy Hoa in Dak Lak Province (formerly Phu Yen Province). Built in 1892 in Gothic style, it is one of the oldest churches in Vietnam. It is notable for its faded grey facade, wooden interior, and as the place preserving the first book printed in romanized Vietnamese by Alexandre de Rhodes in 1651.

Visitors can expect a small, historic Gothic church set in a rural village surrounded by rice fields and gardens. The exterior features a weathered grey facade with a central cross, arched doors and louvered windows. Inside is a vaulted wooden ceiling, stained-glass windows and an altar area. A small grotto and a memorial room display the copy of the first romanized Vietnamese catechism book. The grounds are quiet and open for walking, photography and viewing architecture.

Built in 1892 by French missionary Father Joseph Lacassagne, Mang Lang Church is the oldest church in Phu Yen (now part of Dak Lak) and one of the oldest in Vietnam. Constructed in Gothic style, it has survived for over 130 years. It is historically significant as the place where Alexandre de Rhodes' 'Phép Giảng Tám Ngày' (1651), the first book printed in romanized Vietnamese script (Quoc Ngu), is preserved.

An important Catholic pilgrimage site and cultural landmark for the local community. The church represents the early introduction of Catholicism and Western architecture to central Vietnam and is valued for its role in the development of the modern Vietnamese writing system. It remains an active parish church and a symbol of religious heritage in the region.
