There were several. Miri was one.Scifi has often looked at a post Nuclear age with pockets of humanity scattered around the world as survivors and legends of rebirth after apocalypse...
Even Star Trek has this theme…. I can't remember but think is was mid 21st century...?

The movie Damnation Alley featured a quest to get to one of those pockets near Albany.
