Symbols of Petit Paris: Saigon Church & Central Post Office The Central Post Office and Saigon Notre Dame Cathedral are known as symbols of the French colonial period, and they allow you to feel Ho Chi Minh City as "Little Paris" that has existed for over 100 years. In particular, white doves, which are said to be symbols of peace, sometimes fly around the statue of the Virgin Mary at Saigon Notre Dame Cathedral, and the sight at that time gives you the illusion of having traveled back in time to another world.
