San Pedro de Nora, in addition to the palace complex in Oviedo, now disappeared, consisting of the churches of San Salvador, Santa María and its adjoining palace and chapel (now the Holy Chamber of Oviedo Cathedral, the only one remaining), containing relies such as the Holy Ark and jewels, like the Cross of the Angels, which he donated himself to the Church of San Salvador. Outside Asturias, with the legend of the discovery of the apostle St. James' tomb in Galicia, in a place known as campus stellae (Compostela), Alfonso II had the first church built in the saints honour (year 892). When the Church of San Julián de los Prados, or Santuyano, was built (approx. between the years (812 and 842), it formed part of a series of royal buildings. The church had a basilica ground plan (central nave and two side aisles), separated by three semicircular arches on impost capitals and square columns. It is worth noting the existence of a transept or transversal aisle located between the aisles and the sanctuary, exceeding the central nave in height.

As for the roof, the church had an interesting oaken ceiling carved with a variety of geometric designs. As elements outside the ground plan, there was a vestibule (to the east) and two sacristies adjoining the north and south facades, communicating directly with the transept.

From an ornamental point of view, the murals covering the walls and ceilings of this church are the best-conserved upper medieval paintings in Spain. the technique used is al fresco painting (applied with the plaster still wet), arranged in three well-defined areas.
