Marie Antoinette was apparently exhibited while in prison, is this correct? In the sense that people could visit her like visiting a giraffe in the zoo?

I heard a french historian explain this but I don't know if it is well-known historical fact; he used the animal analogy. I mean, I knew she had no privacy in prison, but this is another level of removing someone's privacy. The historian was saying, people were like: what are we doing this Sunday afternoon? Hey, I have an idea. Let's go for a promenade and visit Marie Antoinette.
