Musée des Lettres et Manuscrits

More than 2,000 documents and letters give an insight into the lives of the great and the good, from Magritte to Mozart. Einstein arrives at the theory of relativity on notes scattered in authentic disorder, Baudelaire complains about his money problems in a letter to his mother, and HMS Northumberland's log-book records the day Napoleon boarded the ship to be taken to St Helena.
