The Mallos de Agüero rise as stone monoliths right beside the town centre. In Agüero, two travel interests therefore meet in a tangible setting: the rocky landscape and the medieval townscape. Anyone choosing a destination that combines cultural and natural attractions can explore these aspects through the local buildings, paths and rock formations.

Rocky Landscapes and Trails

The Mallos are made of conglomerate; erosion shaped their present form. Peña Sola is a monolith formed when a larger mass of rock fractured. On its western side, it reaches a height of more than 200 metres. The geological descriptions emphasise different aspects: for the Mallos, their formation through erosion; for Peña Sola, the fracture of a larger mass of rock and the height of its western side.

There are several climbing routes on Peña Sola. Conditions may vary, so check them before planning a climbing trip. Colonies of birds of prey also nest in the Mallos. This makes the rocky landscape interesting for travellers who want to learn about the local wildlife, too.

The hiking trails offer different perspectives, too. One route near Agüero runs along the right bank of the Barranco de la Rabosera, known there as Pituelo, and offers views of vulture nests. A hiking route near the Mallos de Agüero provides views of the rock formations and their geological unconformities. When choosing a route, you can therefore opt for views of vulture nests or geological structures.

Agüero’s municipal hiking trails are signposted along their routes. Leaflets are available at the town hall or at the Camping Municipal “Peña Sola” site. Check local information before your trip when planning your hikes.

Townscape, Churches and Museum

The ensemble of vernacular architecture adapts the town layout to the uneven terrain at the foot of the Mallos. The medieval townscape is also reflected in the use of stone, in window sills and in coats of arms above doorways. The description thus ranges from the layout of the town to individual architectural details.

The Iglesia de Santiago de Agüero is an unfinished Romanesque church and is protected as a Bien de Interés Cultural (Asset of Cultural Interest). The Iglesia del Salvador dates from the 12th century. The two churches offer different historical points of reference for comparison: Santiago is notable for its Romanesque design, unfinished state and protected status; the Salvador for its 12th-century date.

The Museo del órgano is located in the Casa Abadía. In summer, it is included in the “Puertas Abiertas” programme of the Hoya de Huesca district. If you plan to visit the museum in summer, check local programme information before your trip.

Highlights for Your Stay

Agüero can be planned around clearly distinct themes: the hiking route along the Barranco de la Rabosera combines views of vulture nests with a route along the right bank of the ravine, known there as Pituelo; near the Mallos, the focus is on views of the rock formations and their geological unconformities. For a cultural focus, the two churches offer different historical points of reference, while the museum provides a seasonal addition.
