In a confined area of approximately 30 m², with an average height of 3.50 meters, the Apse contains over a thousand figures. Among these are nearly 500 animal representations and 600 geometric signs or various markings. The figures are distributed across the lateral walls and the domed ceiling, forming a continuous display. Their density increases from the entrance towards the rear, reaching its peak in the absidiole, which opens directly above the Shaft in the most remote section of this chamber. The very soft limestone substrate partly explains the abundance of these graphic elements.
The renown of Lascaux is primarily based on the paintings of the Hall of the Bulls, the Axial Gallery, and the Nave. However, due to the exceptionally high number of figures present in the Apse, as well as in the Passage, the Nave, and the Chamber of Felines, the art of Lascaux is predominantly characterized by engraving.
