Fodor's Expert Review Monasterio de San Juan de la Peña
The origins of this cliffside sanctuary can be traced to the 9th century, when a hermit monk named Juan settled here on the peña (cliff). A monastery was founded on the spot in 920, and in 1071, Sancho Ramírez, son of King Ramiro I, made use of the structure, which was built into the mountain's rock wall, to found this Benedictine monastery. The highlight is the cloister, which is tucked under the cliff and dates to the 12th century. Partially in ruin, it contains intricately carved capitals depicting zoomorphic and biblical scenes of Paradise. The church of the new monastery contains the Kingdom of Aragon Interpretation Centre, where audio guides in English are available.
