The Story

The Royal Collegiate Basilica of San Isidoro stands in the heart of León in northern Spain, along the Camino Francés route of the Camino de Santiago. One of the finest Romanesque ensembles in Europe, it was rebuilt in stone by King Ferdinand I and Queen Sancha over an earlier church dedicated to St. John the Baptist, and was solemnly consecrated in 1063. That consecration marked the arrival of the relics of St. Isidore of Seville (c. 560-636), the great bishop, teacher, and encyclopedist of Visigothic Spain. According to the traditional account, the Muslim ruler of Seville permitted the translation of the saint's body northward so that it could rest in Christian-held territory, and León received it with royal honors. St. Isidore's remains repose today in a silver urn above the high altar. Isidore was among the most learned men of his age. His Etymologies gathered the knowledge of the ancient world for future generations, and his leadership of the Church in Spain earned him the title of Doctor of the Church. His shrine became a center of learning and devotion, and the adjoining Royal Pantheon, with its celebrated Romanesque frescoes, is often called the "Sistine Chapel of Romanesque art." Today the basilica remains a living church served by its cathedral chapter, a treasured stop for Camino pilgrims, and home to a museum housing the Pantheon, an important library, and the famous chalice of Doña Urraca. Pilgrims continue to pray at the tomb of a saint who bridged the ancient and medieval worlds.

Church Recognition

The church holds the rank of a royal collegiate basilica and remains an active place of Catholic worship under the Diocese of León. St. Isidore has been venerated as a saint for centuries and was declared a Doctor of the Church in 1722.

Catholic Teaching

The veneration of St. Isidore's relics reflects the Church's teaching on the communion of saints (CCC 946-962) and on the honor given to the bodies of the saints as temples of the Holy Spirit (CCC 1674), while his life witnesses to the harmony of faith and learning.
