Vienna, SD
Maybe that’s off-topic, but Vienna is a town in Clark County, South Dakota, United States. The population was 78 at the 2000 census.
One of the few pictures I could find on Google:

I think it’s the only place on earth with the name of Vienna that has less than 100 inhabitants. At least if I believe the sources on the Vienna disambiguation page on Wikipedia.


There really arn’t many places in North Dakota with a population MORE than 100.
but it’s south dakota ;-)
