It's actually not a terribly old city anyway. A bit under three hundred years, as I recall, so only a little older than the typical US city.
True, as a city, Saigon is not particularly old. It should be said, though, that before the Vietnamese and the Chinese moved in (as they do), the area was the site of a Khmer fishing village and had been for hundreds of years. The Khmer still haven't got over losing the Mekong River Delta, incidentally, hundreds of years later.
In terms of heritage, it's fast disappearing. Experts have suggested that
more than half the city's historic buildings have been razed in the last decade alone; it's an absolute feeding frenzy. Villas, old department stores, fabulous apartment buildings, theatres - all gone.
Most locals have bigger issues to deal with than history but many are heart broken over what's happened to their city. It's especially tragic when you see heritage replaced by 70-story, half-empty, ego-inflating monstrosities with helipads (for some unknown reason) or worse yet, a shopping mall. It's straight out of the
I-don't-give-a-f*ck-where's-my-money handbook.
