Just had to share this posting and photo from Greater Greater Washington. (It’s a favorite local blog of mine.) This is a 1959 artist’s rendering of what might have been The Kennedy Center, then referred to as the National Cultural Center.
Personally, I like this 1959 design better. The building is joined with the Potomac River. I have never figured out why the current building is cut off from the water. We seem to deny our waterfront.
