Whether by day or by night, the abbey of Mont-Saint-Michel is a delight for the eyes and the mind. It has the particularity of being built on a rocky islet surrounded by a magnificent bay, home to the highest tides in continental Europe. The Mont and its bay are a UNESCO World Heritage Site. The dawn is always full of promise and the richly coloured sky is a joy for amateur and professional photographers alike. Seen from afar, its magical castle silhouette is gradually revealed in the emerging light.
