Where did all the Bastille bricks go?

I'm giving another nod to the French today because it's Bastille Day.  But did you know there's no longer a Bastille to celebrate?  Not even a brick.  What's there instead is a public square with a structure in the middle of it marking the spot where the french prison once stood and subsequently where Marie Antoinette lost her head.

• Date Created/Published: [between ca. 1890 and ca. 1900]

When I saw this picture, I about lost my head too; well, at least to a little wonderment as I realized how it so closely resembled a structure I had just seen in person on our recent visit to the U.S. Military Academy in West Point, NY.

Could there be a connection between these two monuments?

After a few google searches and a few wiki pages later, the answer I came up with wasn't what I had hoped for.  As it turns out, they were designed by two different artists in completely different circles of influence.
