During the last world war the town of Caen was almost completely destroyed. The valuable collections of the Caen herbarium (CN) were evacuated and were thus saved. It is now twenty years after the war. The town of Caen has been beautifully rebuilt and the newly erected buildings of the university are very impressive. This university, founded in 1432, is now said to be not only the oldest but at the same time the most modern in France. Although the herbarium is now in a modern building, this does not mean that it is managed in a modern way.
