Filming in Ho Chi Minh city, Vietnam
As the biggest city in Vietnam, Ho Chi Minh city is among top filming locations in Vietnam. Though doesn’t have lots of lakes like in Hanoi, Ho Chi Minh city has its own attractions and stories.
Notre Dame cathedral was built by French colonists. Currently it has been going under renovation for 2-3 years, and this process would take much longer. It’s very hard to ask for filming permission inside the Cathedral, they’re almost non-accessible by phone. However, you can try to contact them via Vietnam Board of bishop.
