Cova des Càrritx

Cova des Càrritx is an archaeological cave set on the western slope of the Algendar ravine, within the municipality of Ciutadella de Menorca on the island of Menorca. Discovered in 1995 by local cavers Pedro Arnau and Josep Marquez, it has become one of the most significant prehistoric sites in the Balearic Islands, prized for its well-preserved traces of ritual and funerary use spanning thousands of years.

What does the cave look like inside?

The cave extends for roughly 170 metres and is made up of seven interconnected chambers linked by narrow passages. Its interior is decorated with numerous stalactites and stalagmites, and the entrance was once sealed by a cyclopean wall — a construction of large, roughly hewn stone blocks typical of the island's prehistoric architecture.

What traces of the past have been found here?

Research has shown that the cave saw human activity across several distinct periods: the late Chalcolithic (end of the 3rd millennium BC), the Bronze Age (2nd millennium BC), and again during the Almohad period in the 13th century AD. The Bronze Age phase carries the greatest significance, when the cave served as a site for rituals and burials.

In one of its more hidden chambers, numbered 5, archaeologists uncovered an unusual deposit: wooden containers and horns filled with locks of human hair. That very deposit later became the basis for a landmark scientific study.

Why is Cova des Càrritx internationally known?

Chemical analysis of the preserved hair allowed researchers to detect psychoactive substances consumed by Menorca's inhabitants roughly 3,000 years ago. The findings are considered the first direct evidence of drug consumption in prehistoric Europe, turning Cova des Càrritx into a reference point in archaeology and in the study of prehistoric ritual practices.

Who should visit this site?

Cova des Càrritx appeals mainly to visitors interested in archaeology, prehistory, and Menorca's natural heritage. Given the scientific importance of the site and the sensitivity of its finds — including human remains — access can be restricted or may require prior arrangement; this is not a typical open-access tourist cave but a site of considerable research value. The surrounding Algendar ravine itself makes for a worthwhile stop when exploring the island's western countryside.
