The monastery grew in importance thereafter, acquiring numerous properties and wealth during the first and middle stages of the Kingdom of Navarre, thanks to the privileges and donations made by the Navarrese kings.
Since then it has been in various states of repair, undergoing many expansions and remodelling (the most extensive carried out in the sixteenth century, when almost the entire monastery was rebuilt).
Romanesque architecture pieces have survived until the present day (such as the church, with its Porta Speciosa), as well as parts that are even more ancient such as the notable crypt.
In June 2015, the monastery was the setting for the first official visit of Felipe, Prince of Asturias as King of Spain with his wife Princess Letizia.
[1] The monastery is located on one of the various routes of the Way of Saint James coming from the Corridor of Berdún and Jaca.
