The Cave of Altamira is a famous prehistoric site located in northern Spain, known for its remarkable cave paintings. Discovered in 1868, the cave features vivid depictions of bison and other animals, created by early humans around 36,000 years ago. These artworks are considered some of the finest examples of Upper Paleolithic art. The cave is part of the Altamira National Park and has been designated a UNESCO World Heritage Site. Due to concerns about preservation, access to the original cave is restricted, but replicas and virtual tours allow visitors to appreciate its historical significance and artistic achievements.
