The caves were carved into the hillside to utilize the natural thermal insulation of the rock, keeping interiors cool in summer and warm in winter.
The dwellings were officially abandoned in 1965 following a government initiative to move residents into modern brick housing.
The local terrain is composed of gypsum, which is highly susceptible to erosion, necessitating periodic maintenance of the cave faces.
Some caves include remnants of traditional whitewashed facades and wooden doorways that were added during the late occupation period.
The site overlooks the valley of the Ebro River, a critical strategic location in Navarran history.
Many of the caves were originally excavated by agricultural laborers who needed proximity to their fields in the Bardenas Reales.
The cave complex is often referred to as the 'Barrio de las Cuevas'.
Cuevas de Arguedas consists of traditional cave dwellings carved directly into the soft clay and gypsum cliffs of the Balcon de Pilatos. These dwellings were inhabited by local families until the mid-20th century, specifically until the 1960s. The site represents a unique troglodytic architecture style common in the Bardenas Reales region. Visitors can view the exterior facade and several preserved internal structures that reveal the layout of historical cave living. The site is situated on a hillside overlooking the town of Arguedas, providing a clear view of the surrounding landscape. The soft geological composition allowed residents to manually excavate chambers for housing, stables, and storage. It is an open-air historical site maintained as a cultural landmark.

Wear sturdy, closed-toe shoes as the terrain around the cliff base is uneven and dusty.
Visit during the shoulder seasons to avoid the extreme heat often trapped by the clay cliffside during summer.
Keep a safe distance from the cliff edge as the gypsum rock is brittle and prone to minor rockfalls.
Do not attempt to hike up the cliffs behind the designated viewing areas, as the clay composition is unstable.
Respect the site as a historical monument; do not climb on restricted areas or attempt to enter unstable sections of the caves.
