I am working on a personal project to photograph historic bank buildings in the United States.
My current "to do" list includes buildings that:
(1) have been included in the National Register of Historic Places (NRHP),
(2) housed (or currently house) financial institutions in the past.
Here is my list in Excel spreadsheet format.
I plan to visit every single one building in the list in the next several years, and potentially may publish a book based on my photography collections.
I also created a customized online map on which you can easily locate these buildings.
Here is a KML file that you can use in Google Earth software.
