During the Civil War, the monastery was looted and partially burned. Nuns and their heritage were forced to flee. Many works were transported to Catalonia, sparking a heritage conflict that is still ongoing. In recent decades, works of art have been judicially returned from Catalan museums to the Sijena Monastery, turning the site into a symbol of memory, historical justice, and Aragonese heritage. Its isolated location in the Monegros mountains is part of its charm. The arid surroundings contrast with the monumentality of the building, giving it an almost mystical feel.

It's very well set up, the only thing is that it's packed with people and some stop wherever they can without realizing that they're in the middle of the route, hindering those who have no intention of stopping. In my case, in this 2025 edition, I only made a brief stop at the third refreshment station.

This impressive hillock is a typical natural formation of Los Monegros. A hillock is an isolated hill or mound formed by wind and water erosion. The softer layers of the soil erode over time, leaving only the most resistant rocks standing. That's why they have such unusual shapes, like natural sculptures. They are true symbols of the Monegros landscape, solitary and surrounded by arid terrain.
