Mont- Saint Michel
This castle monastery combination along the Northern French coast, looks like something right out of a story book. The location became the seat of the monastery from which it draws its name some time during the 8th century. During tidal shifts the Mont can become completely surrounded by water making it easy to defend when under siege. Today Mont Saint-Michel is a World Heritage sight with a population of 44 people. I had the pleasure of visiting this sight back in 2009 and it was one of the most spectacular locations I have ever visited. If you are ever in France near this area I highly suggest visiting it.
