This list contains more than 700 buildings in the United States that are underground, either completely or to a significant extent. It also includes a few that are under construction or are being planned. The list is incomplete for several reasons. Private homes are not included, except for one located in a former missile silo and one that is located in a sculpture garden that is open to the public. Wineries with cellar space open to the public are included only if they are outside of California; in addition, there are more than 100 California wineries, some of which have underground installations large enough to contain offices and production facilities as well as aging cellars (for a partial list, see Building Caves: Wine Not?). Most of the buildings listed below were identified through descriptions published in newspapers, magazines, and books. If you have additions or corrections for this list, please send us information. Thank you!
