7. Paper Museum
Papermaking was big business in the Charente Valley because of the outstanding water purity, and a piece of this history is maintained at a former mill on a river island.
This facility shut down in the 1970s and had been running since 1887. Nothing was removed when it closed, so you can check out a lot of old industrial machinery, including the working water wheels powered by the river.
This factory churned out cigarette paper and has even kept the rollers that created the watermarks on each sheet.
There are broader exhibits about the story of industrial papermaking in the 19th and 20th centuries, with documents, first-hand accounts and black and white photography.
