The Notre Dame Cathederal in Ho Chi Minh City was established by French Colonialists following the conquest of Cochinchina and Saigon.
It’s design is somewhat reminiscent of Notre Dame in Paris, with the exception of the spires on both bell towers, and the color. All of the materials were imported from France during construction.

As you can imagine, this is a big tourist spot. Combined with the Saigon Central Post Office being located across the street, this is a prime breeding area for vendors and scammers.

The cathedral does have limited visiting hours.
The entirety of the cathedral is also not accessible to tourists.
The interior is artfully decorated in white with wood accents.

Notre Dame Cathedral is well worth a visit, but prepare to be patient if wanting to take a picture without any tourists invading your photo.
