These two caves, located about a half-hour drive southeast of Poitiers in western France, were inhabited about 14,000 years ago. While the cave walls were not decorated, the inhabitants left behind thousands of limestone pieces that have engravings on them. There are animals and a good number of human representations on these pieces, some of which are on display in the town's Musée de Préhistoire de Lussac-les-Châteaux. It is in a building called La Sabline that also serves as the town's cultural center. These links show you some of the art that has been found in La Marche and Fadets caves.
The caves are open for guided tours, but there is no art to be seen. The tour is in French only and covers the history of the caves. Tours start at the museum and it is about a 10 minute walk to the caves. The caves are not accessible to people with disabilities, but the museum is.
Cave tours are given every Wednesday at 3pm and 5pm. There are more tours in the summer, check the "agenda" tab on their website for details. There is a train station in town, and it is a 600 meter walk from there to the museum.
