This museum has the best collection of paleolithic artifacts in the world, but only a small fraction are on display. Located on the outskirts of Paris in the former royal palace Château de Saint-Germaine-en-Laye, this museum houses thousands of objects from all over France from the Paleolithic through the early middle ages. Among the highlights of the collection are the original carved blocks from Roc de Sers and Roc aux Sorciers.
In 1904, Edouard Piette donated his extensive collection of prehistoric artifacts to the museum, with the stipulation that they be displayed according to his wishes. Today, the Salle Piette is open for guided tours a few days a week. Click here to see information on reservations (in French).
Unfortunately, there is very little information here in English, but you can still see some amazing artifacts.
