The Decorated Caves of the Vézère Valley are a series of prehistoric caves located in southwestern France, near the town of Les Eyzies. These caves contain some of the finest examples of Paleolithic cave art in the world and have been designated a UNESCO World Heritage Site.

The caves were inhabited by humans during the Upper Paleolithic period, approximately 20,000 to 10,000 years ago. The art in these caves includes paintings, engravings, and carvings of animals, humans, and abstract designs. The art was created using various techniques, including finger-painting, blowing pigment through a tube, and using brushes made from animal hair.

The most famous cave in the Vézère Valley is Lascaux, which contains some of the most impressive examples of Paleolithic cave art in the world. The cave is divided into several chambers, with the most famous being the Hall of the Bulls, which contains paintings of bulls, horses, deer, and other animals.

Other notable caves in the Vézère Valley include Font-de-Gaume, which has some of the last remaining polychrome cave paintings in France, and Rouffignac Cave, which features engravings of mammoths, horses, and bison.

While some of the caves are open to the public, access is limited to protect the delicate artwork. Visitors can see replicas of some of the most famous paintings, and there are several museums in the area dedicated to the study and preservation of Paleolithic art.
