Around 910, an abbey was founded which was to become the largest that Christianity knew in the Middle Ages: the Abbey of Cluny. In barely 200 years, it had woven a network of monasteries throughout Europe that stretched from Ireland to the Holy Land and from Poland to the Iberian Peninsula. Its power and influence transcended regional kingdoms, being a 'church within the Church', accountable only to the Holy See.

Currently, more than 200 Cluniac sites throughout Europe, federated in the Fédération Européenne des Sites Clunisiens, are part of the Great Cultural Itinerary of the Council of Europe. In Spain, we are part of Cluny Ibérica - Sitios Cluniacenses being witnesses of this invaluable heritage, great artistic and cultural landmarks of our country of Cluniac past, such as San Juan de la Peña (Jaca, Huesca), San Salvador de Oña (Burgos), San Martín de Frómista (Palencia), San Zoilo de Carrión de los Condes (Palencia), San Benito and San Pedro de las Dueñas in Sahagún (León), San Salvador de Cornellana (Salas, Asturias), San Salvador de Nogal las Huertas, San Román de Entrepeñas in Santibáñez de la Peña, Santa María de Mave or San Pedro de Villalcázar de Sirga (Palencia).

A good example of the leading role they played is that they were chosen as the royal pantheons of the most powerful lineages of the medieval kingdoms, such as San Juan de la Peña and the kingdom of Aragon, San Salvador de Oña in Castile or San Benito de Sahagún in León, which guard the remains of Ramiro I, Sancho III or Alfonso VI, among many others.

A route that allows you to soak up the origins of the historic kingdoms of Spain through one of its main protagonists, the Cluniac monasteries. The once great lordships are today located in rural areas of great scenic wealth, providing the backbone for a whole series of corners around them that are waiting to be discovered. They are privileged enclaves in the territories of Aragon, Castile and Leon and Asturias which, in combination with their varied gastronomic virtues, offer visitors an experience that brings them closer to the experience of the ancient monks, being able to tour the territories of their domains, their incomparable temples and cloisters and even, in some, to spend the night within their walls as in medieval times, but with the comforts of the 21st century.
