The Nha Trang Cathedral (Nhà Thờ Núi) is the city's Catholic church, built by French missionaries on a granite outcrop in the 1930s. The building is a striking piece of French colonial ecclesiastical architecture — grey stone, neo-Gothic proportions, pointed arches, and a bell tower that rises above the surrounding neighbourhood. It is one of the more photogenic buildings in Nha Trang.
The interior is cool and moderately decorated, with stained glass windows and a simple stone altar. Masses are held daily, and the church is genuinely active. The hillside setting, reached by a staircase from the street, gives good views over the adjacent railway station and the surrounding streets.
