This is a list of 675 underground structures in the U.S. They include subterranean shopping malls, museums, public libraries, churches, gardens, parks, tunnels, observatories, restaurants, hotels and many other interesting places.
I cannot guarantee the total safety of all of these structures, but in the event of a disaster, it will likely be safer underground.
If you don’t have any better options, I recommend one of the subterranean places near you: See the complete list at: www.subsurfacebuildings.com
A partial list: Building Caves: Wine
The list is incomplete for several reasons.
