The Toll caves were formed in calcareous rocks from an old coral reef 38 million years ago, when the underground river formed cavities of great beauty. Also known as the ‘Palau de la Fauna del Quaternari’ (palace of the fauna of the quaternary), this is one of the most important palaeontological sites in Europe. On an archaeological scale, remains of human presence from the Middle Palaeolithic to the Bronze Age have been found with a considerable number of burials and other materials from the Neolithic period.
The remains of these beings and their activities were accumulated, along with the sediments dragged by the floods of the torrent forming layers. These layers present an authentic archive of the history of the cave over the last 100,000 years. Thirty-five different species of mammals have been found in the excavations, some of which are now extinct.
For more than 3,000 years, the cave was sealed by a landslide on the slope, which hid the southern mouth. This has allowed the sediments to maintain intact until now without anyone removing them, constituting a type of time capsule.
To complete the experience, we recommend a visit to the Archaeological and Palaeontological Museum of Moià, located in the house where Rafael Casanovas was born.
The Toll caves can be visited on weekends and holidays and educational activities and programs are organised for groups. The archaeological museum can also be visited during the week.
