The Nha Trang Cathedral, located on Bong Mountain, is 12 meters high and is a lovely example of French architecture. It was built by Fr. Louis Vallet, with work starting in 1928 and being completed in 1933. His grave is placed at the foot of the Bong Mountain.
To create space on the top of the mountain to build the church, about 500 mines were reportedly used. The church is built with gritstone and concrete bricks. Its architecture is similar to its peers in Sa Pa and some other places in Vietnam.
