This former royal palace owes it's fame to the imprisonment of Marie Antoinette (wife to King Louis the… wait, XVI? Dina's going to shake her head at me dismally for not knowing that, but it's still not going to make me remember) right up to moments before her death. It housed many a prisoner during the French Revolution (an event which I need to pain-stakingly research before I can pretend I know enough about to share with you) but mostly showcased the specific areas to which Marie and other prisoners were held and their treatment on the site.
Just a pretty cool work of Gothic architecture with a whole lot of stained glass, really. Well, maybe a bit more than that. Each window tells a biblical story from start to finish in stained glass imagery, and these are big impressive windows. None of this 4 or 6 pane business, they are probably 15 metres in height and another 4 in width.
Admittedly this was not as impressive as I imagined it to be. Especially after I discovered that the Hunchback of Notre Dame was simply a fictional story and not based on any history whatsoever. I mean, I didn't think a hunchbacked man really lived in the North Tower and rang the bell. But it would have been nice.
