Built above the caves where San Millán once lived, the Monasterio de Suso was consecrated in the 10th century. It’s believed that in the 13th century a monk named Gonzalo de Berceo wrote the first Castilian words here. It can only be visited on a guided tour. Tickets must be bought in advance and include a short bus ride up to the monastery.
You can reserve tickets by calling ahead, or you can pick them up at the very helpful tourist office at the Monasterio de Yuso. Maps detailing short walks in the region can also be obtained at the tourist office.
