The cave paintings of Lascaux, discovered in 1940 and opened to the public in 1948, were closed to the public in 1963 due to degradation caused by so many people just going and looking at them. Replicas of the paintings have been produced since and are the primary objects of study. The opening of Lascaux Cave after World War II changed the cave environment. The exhalations of 1,200 visitors per day, presence of light, and changes in air circulation have created a number of problems. Lichens and crystals began to appear on the walls in the late 1950s, leading to closure of the caves in 1963. This led to restriction of access to the real caves to a few visitors every week, and the creation of a replica cave for visitors to Lascaux. In 2001, the authorities in charge of Lascaux changed the air conditioning system which resulted in regulation of the temperature and humidity. When the system had been established, an infestation of Fusarium solani, a white mold, began spreading rapidly across the cave ceiling and walls. The mold is considered to have been present in the cave soil and exposed by the work of tradesmen, leading to the spread of the fungus which was treated with quicklime. In 2007, a new fungus, which has created grey and black blemishes, began spreading in the real cave.
As of 2008, the cave contained black mold. In January 2008, authorities closed the cave for three months, even to scientists and preservationists. A single individual was allowed to enter the cave for twenty minutes once a week to monitor climatic conditions. Now only a few scientific experts are allowed to work inside the cave and just for a few days a month, but the efforts to remove the mold have taken a toll, leaving dark patches and damaging the pigments on the walls. In 2009 the mold problem was pronounced stable. In 2011 the fungus seemed to be in retreat after the introduction of an additional, even stricter conservation program.

Most cave paintings are high-quality abstracts. To be cave-capable, an artist had to first develop their skill elsewhere.

If somebody takes a torch in the cave, they’ll see it.
