Ice Age Cave Art Sat Unnoticed at a Catalan Tourist Cave for Decades

Archaeologists have recorded 280 Ice Age engravings at Cova de la Font Major in Catalonia — one of the largest assemblages of Paleolithic rock art (art from the Stone Age, roughly 2.5 million to 10,000 years ago) ever documented in the Iberian Mediterranean. The find, made in 2019 at what is already a tourist attraction, was described this month in the journal Antiquity.

The location is the story's twist. More than half of all Paleolithic rock art recorded in Europe sits in the Iberian Peninsula, but scholars long believed it was rare in the northeast. This discovery upends that assumption, and it suggests two things: the regional population was larger than previously thought, and it had artistic traditions of its own.

How did the art go unnoticed?

The cave has a long history of visitors — at least 900 years of them, judging by the engravings and graffiti on its walls. Its main entrance collapsed sometime during the Roman period (2nd–5th centuries CE). An inscription dated 1199 records an entry in the second millennium, perhaps through a fissure.

The modern timeline runs like this:

• 1853: the cave was entered through a private well, with only sporadic visits recorded afterward
• 1956: members of the Centre Excursionista Pirinenc explored and surveyed it
• 1957: the town council of Espluga de Francolí cleared the entrance for visitors
• 1993: the cave was converted into a museum
• 2011: researchers confirmed part of the original entrance, destroyed in 1957, had survived
• 2018: the site joined a research project
• 2019: during excavation, one of the authors noticed some marks among the graffiti looked Paleolithic

That moment of recognition came after generations of foot traffic. "For more than six decades, thousands of visitors passed directly in front of the engraved surfaces, and in some cases inscribed names and dates over them, without the Paleolithic origin of the figures being recognized," writes research co-author Josep Maria Vergès of the Catalan Institute of Human Paleoecology and Social Evolution (IPHES-CERCA).

What does the art look like?

The engravings sit in a series of small galleries. They include depictions of animals and groupings of abstract marks, notably one composition of hundreds of loop-shaped incisions.

The technique is what stands out. Uneven conglomerate rock — a coarse rock made of cemented fragments — is theoretically unsuitable for cave art. Here the artists worked with it instead of against it, incorporating the irregularities into their compositions. They used junctures between two kinds of rock as ground lines for figures, and in one rendering of drinking deer they turned a fissure into a water surface.

What does this change for Paleolithic studies?

The discovery redraws the map of where Mediterranean Ice Age art was made, and how varied it was. "The Mediterranean art of western Europe is now enriched by a new body of rock art," states Vergès, "which allows us to characterize in greater depth a Mediterranean graphic tradition with an identity of its own."

The study also flags a practical lesson for the field: sometimes major finds aren't hidden in sealed caves — they're on the walls of sites the public has been walking through for decades.
