Ho Chi Minh City is perhaps Vietnam’s most buzzing city. Also known as Saigon, it played an important role during the Vietnam War and saw some of the most pivotal moments in the country’s history, including the formal reunification of Vietnam, which marked the end of the war. Today, it is a hub of commerce and culture that helped propel the country’s tourism. Some of the most remarkable works of architecture in Vietnam can be found in the city like the Notre Dame Cathedral of Saigon and the Central Post Office—remnants of the time when the country was part of French Indochina in the 19th century.
