Cueva de los Cien Pilares
La Rioja
The Cueva de los Cien Pilares is an intricate complex of rock-hewn galleries and chambers located beneath the Cerro de San Miguel in Arnedo, La Rioja. This unique site dates back to the Middle Ages when local inhabitants sought refuge from insecurity by excavating caves into the soft sandstone and clay hills. The caves feature pillars supporting ceilings, interconnected rooms, and openings such as doors and windows carved into the rock face, creating a striking visual impression. Historically, the complex likely housed the Monastery of San Miguel, referenced in 11th-century documents, although no medieval architectural remains survive except for the hermitage atop the hill. The site exemplifies rupestrian architecture and is part of the Caminos del Arte Rupestre Prehistórico (CARP). The visitor experience includes a guided tour of the caves and an Interpretation Center that recreates traditional cave homes and agricultural-use caves, reflecting the lifestyle of hundreds of families who lived in cave dwellings up to the mid-20th century. These homes maintained a constant temperature year-round and featured a central corridor distributing rooms such as kitchens with natural ventilation, bedrooms, and stables. The caves also served economic functions related to agriculture and livestock, including cellars, corrals, beekeeping spaces, wood storage, haylofts, and dovecotes. Since 2014, the complex has been adapted for tourism, with guided visits available by reservation through the Arnedo Tourist Office. The site offers a rare glimpse into medieval refuge architecture and the traditional cave-based lifestyle of the region, making it a culturally and historically significant destination in La Rioja.

Histoire
The origins of the Cueva de los Cien Pilares date to the Middle Ages, a period marked by insecurity that prompted inhabitants of the Cidacos Valley to seek shelter in rock-cut caves.
In the 11th century, the caves likely served as the Monastery of San Miguel, as documented by a will from 1063 by Sancho Fortunionis, Lord of Arnedo.
Over the centuries, the caves evolved from religious refuge to residential and economic uses, with hundreds of families living in cave homes until the mid-20th century.
The development of Arnedo's footwear industry and socio-economic progress led to the gradual abandonment of cave dwellings.
Since 2014, the site has undergone restoration and adaptation for tourism, culminating in a comprehensive visitor center and guided tour by 2016 and expanded interactive experiences by 2020.
