09:00 to 09:30 · The French quarter by motorbike
This stretch is best taken in motion, so we ride it. Ninety minutes of queueing becomes thirty minutes of seeing more.
The Saigon Opera House, built 1900, ornate to the point of showing off. The People's Committee building, 1898 to 1909, pale cream and unmistakably an argument about who was in charge. In front of it, the statue of Hồ Chí Minh looking down Nguyễn Huệ Walking Street, pedestrianised in 2015.
There is one spot where the colonial city hall sits behind him and the busiest square in modern Saigon opens in front. Your guide knows it. That single frame holds a century.
We stop for coffee on the kerb if you want it. You should.
09:30 to 10:15 · Notre-Dame Cathedral and the Saigon Central Post Office
Notre-Dame Cathedral Basilica, built between 1863 and 1880, has been under restoration since 2017 and the interior remains closed. We look at it from the square. Anyone promising you the inside right now has not been in recently.
Directly opposite, the Saigon Central Post Office, finished in 1891 to a design by Alfred Foulhoux, built like a French railway station. You will read almost everywhere that Gustave Eiffel designed it. He did not.
It is still a working post office, which is the point. Buy a card, pick a commemorative stamp, write it at the wooden benches and send it home. It lands on your doormat about three weeks after you do.
