Nothing remains of medieval monastery. Between the 16th and 18th centuries the monastery reached its maximum splendour, giving us the buildings we see today. The monastery suffered two major fires.  

The first was in 1526, when Navarre lost its independence, and the second, in 1793, during the rule of the National Convention in France, when French troops invaded the area and razed the monastery and the town of Urdax to the ground. In the second fire, the monastery's great library, which contained over 9,000 volumes, was destroyed. After the National Convention (1793-1795), the monks had to take refuge in the Sanctuary of Loyola until 1806.

Shortly after that, the confiscation of Church property led by Mendizabal took place in 1836. The Premonstratensians left the abbey forever and the church became a parish church. Only the church and the cloister remain of the old monastery. Together with other spaces in the building, it now houses the monastery museum, a collection of art, and a pilgrims' hostel.

The Museum of Liturgical Ornaments, promoted by the Association of Friends of the Camino de Santiago of Urdax-Baztan, is also located in the old monastery, as is a permanent exhibition on 50 years of Basque painting. 

A must see :  EXPO-ZUBI-ARTE present in the cloister, the permanent exhibition “50 years of Basque painting and sculpture” is open during regular museum hours.
