To my shame, when I came to the 38-meter-high Bong Mountain (taking into account the height of the mountain towering over the city by 50 meters) I couldn't figure out which side of the entrance was to the Catholic Neo-Gothic cathedral. It turned out that it was located a little to the side, plus crowds of local residents swirled around and obscured the view - it was some kind of religious holiday. St. Mary's Square was spread out around the temple, along which I poked back and forth in search of an entrance. But still, I examined this iconic building of the colonial era.. The Catholic Cathedral of Christ the Tsar was built in 1933, during the 100-year French rule under the leadership of Archbishop Louis Vallee. That's why it reminded me so much of the numerous Paris cathedrals I've visited. However, it feels like the cathedral here is in completely different shades, not so gloomy, perhaps because it was built of local gray stone and brick. I liked it very much. It was as if I had fallen out of Vietnam for a while, but looking around carefully, I realized that I hadn't fallen out.. Still, I'm in Vietnam. Great place!
For a "check mark", you can visit. There's nothing special, just another tourist spot, but if you haven't been to Catholic cathedrals before, it will be interesting.
