One task that has been successful is the restoration of the original entrance to allow sunlight to enter the cave.
In 1999, a handful of researchers witnessed this event for the first time in 15,000 years.
In other words, the cave painting at Lascaux is most likely to date back to about 15,000-17,000 BCE, with the earliest art being created no later than 17,000 BCE.
Furthermore, the unity of style found in the drawings and engravings at Lascaux, indicates that most were created during a relatively short period of time, perhaps less than two millennia.
Alternatively, to compare Lascaux with the earliest caves, see: El Castillo Cave Paintings (39,000 BCE).
To understand how Lascaux's cave painting fits into the evolution of Stone Age culture, see: Prehistoric Art Timeline.This view is further supported by the 'Placard type' style of geometrical signs in the cave.According to paleolithic scholar Jean Clottes, they are very similar to the 'chimney' signs found in the Pech-Merle cave paintings (Lot, France), whose art dates back as far as 25,000 BCE.In 1983, an exact replica of the Great Hall of the Bulls and the Painted Gallery - created under Monique Peytral and known as "Lascaux II" - was opened a few hundred metres from the original cave, and it is this replica that visitors see today.In addition, a full range of Lascaux's parietal art can be viewed at the Centre of Prehistoric Art, located close by at Le Thot.
As one enters the main area (the Rotunda) the first image one encounters is a horse's head and neck with a fuzzy mane. Other notable pictures found in the Hall of the Bulls include the Frieze of the Black Horses (a long line of aurochs and horses), the Frieze of the Small Stags, heads of some six bulls, a headless horse and a bear.
