Perhaps because of the French colonial relationship, Catholicism seems to be prevalent in Vietnam. Every city has a famous Catholic Church, and the most famous Catholic Church in Vietnam comes out of Hanoi, the other is Ho Chi Minh. Ho Chi Minh's Notre Dame Church of Saigon was built about 150 years ago. He is also the Cathedral of the Catholic Church of Ho Chi Minh City. The whole church is a typical Gothic building. It is said that all the raw materials are from France. Because the whole traffic system is made of red brick, it is also called the Red Church. It's also a must-see spot for Ho Chi Minh City's inbound tour. You can see the church about 900 meters along Nguyen Du Road from the Unified Palace. It's very eye-catching. The church is open to the outside world without admission tickets. The time is from 8:00 to 11:00 in the morning and from 15:00 to 16:00 in the afternoon. Mass is held every day at 5:30, 17:00 on weekdays, 5:30, 6:30, 9:30, 16:00, 17:15 and 18:30 on Sundays. If religious, it is suggested that a mass be held together. A Mass is about 1.5 hours. Vietnam's tourism is really a "leisurely" one. Don't rush too fast. It's totally no problem to set aside this one and a half hours. During Mass, my personal advice is not to take any more pictures. You can take a good picture after the mass. The interior decoration of the church is also more traditional Catholic style. The tall dome gives people a sense of reverence for the Holy Father when they are in it. All the glasses are colored glasses, which make up the stories in the Bible and deserve to be savored carefully. In addition, in front of the church, there is a statue of the Virgin Mary, which was presented by the Roman Church in 1945. So back to the Virgin Mary and take a picture of the whole church is the most complete. However, because it is a popular tourist spot, there are often too many buses and minibuses parked in front of the church, which is very eye-catching. There is really no other way to take a clean picture except to wait. Next to the church is the Central Post Office. These two scenic spots can be visited together.
