The Cave of Maltravieso was discovered in 1951 when construction workers blasted through the rock during building works on the city's edge. Inside they found a Palaeolithic cave decorated with hand stencils and animal engravings. The cave has been closed to direct public entry since its discovery (as with Altamira, open access causes rapid deterioration), but visits are possible through guided tours to a designated viewing area.
A small interpretive centre near the cave entrance explains the significance of the finds in some detail. The hand stencils — made by pressing a hand against the rock and blowing pigment around it — are the dominant motif, along with some rare hand outlines and geometric shapes. The cave's significance increased enormously after the 2018 dating results. Book tours through the city's tourism office; availability is limited.
