Mont St. Michel is the second most popular place to visit in France (next to....the Eiffel Tower of course!) and is a huge "castle" built almost on it's own island in the ocean. It has been used for everything from an abbey (we visited on a Sunday and mass was actually happening in the chapel) to a stockade during the Revolution.
It was about a 4-hour drive through beautiful countryside (paysage) with stone houses, hedge rows, crops and lots of sheep and cows. Check out pictures tomorrow on the flickr link!
