This museum was created in 1881 by the Scotsman Jack Miln. This collection grew richer thanks to the collection of Zacharie Le Rouzic, an inhabitant of Carnac. Here you will find a large number of objects belonging to the Palaeolithic burial furniture: jewels, polished axes, pendants, pottery pieces, etc. The Roman period can also be seen here as well as the Breton Middle Ages and the excavation methods used by the farmers.
