Aren, a story among dinosaurs, stone and memory

Arén is a small municipality in Ribagorza that preserves its medieval layout, with streets that climb up to the remains of the old Arén Castle , located in the upper part of the town.

The municipality comprises charming and peaceful small villages: Berganuy, Betesa, Campamento, Claravalls, Iscles, Los Molinos, Obis, Puimolar, Ribera de Vall, San Martín, Santa Eulalia, El Sas, Sobrecastell, Soliva, Soperún, Suerri, and Treserra. They all share a privileged natural environment and a heritage that deserves to be discovered at a leisurely pace.

Walking through Arén is like opening a history book: the past is written in its stones, and the origin of life is revealed in its hills, thanks to the paleontological remains that have placed it on the international scientific map.

Dinosaurs and heritage that leave a mark

Over 70 million years ago, the last dinosaurs in Europe lived in this area. Among them was a complete hadrosaur skeleton found within the municipality and now housed in the Dinosaur Museum of Arén . A must-see for families and anyone curious about natural history.

Besides its paleontological value, Arén was declared a Historic-Artistic Site in 1982 for maintaining its original urban layout. The remains of its medieval castle can still be seen atop the village, a reminder of its strategic importance in the Middle Ages.

The Hermitage of the Virgin of Regatell , the natural viewpoint of Betesa or the tranquility of Sobrecastell complete the visit for those looking for authentic and unhurried tourism in Arén .
