Went there a few months ago, just before the outbreak shut everything down. It is beautiful. The streets are almost alley like, narrow and winding up the mountain with shops on each side. It felt like stepping into another time.
Even better, most of the time it isn't a field but a flood plain. When I went it was was sand almost to the horizon where you could just make out the sea. It also has some of the highest tides in the world. A few times during the year, when conditions are right, it literally becomes an island, with the causeway out to it being completely submerged.
I've been there and it was one of my favorite places in France! I have some beautiful pictures from my trip there. @that_creepy_guy I believe this was the inspiration for the castle in the Disney movie Tangled.
Pics of my trip. Sorry for the formatting, had to break up the url.
