The Orreaga-Roncesvalles Collegiate is considered the most French church on the peninsula and stylistically, it belongs to the best French Gothic style of its day (XIII century). It was built using limestone from Auritz-Burguete. The prize piece is the image which presides over the Collegiate: a silver-lined carving of the Virgin with child.

A XVII-century cloister replaces the earlier Gothic cloister, which collapsed after a great snowstorm and later burned. The Chapterhouse or Chapel of San Agustín dates from the XIV century and houses the tomb of Navarre’s founding monarch, Sancho the Strong, winner of the Battle of Navas de Tolosa. The tomb includes a gigantic, life-size, statue of the king lying on top which bears witness to the extraordinary size (2.25 metres tall) of the “strong king”. The statue was rescued after lying buried from 1622 to 1890.

The Chapel of Santiago or the Holy Ghost is also known as the Silo of Charlemagne. The story goes that the Twelve Peers of France killed at the Battle of Roncesvalles are buried inside. The Museum exhibits what is known as Charlemagne’s chessboard as well as a beautiful collection of paintings and gold work.
The Hospital and Itzandegia (interpretation centre) are other unique elements comprising this extraordinary complex. Guided tours are available to learn more about the Collegiate; find out more from the tourist office located in the complex itself.
The Collegiate is a significant centre of popular religious worship. From April onwards, all of the valleys in the area hold processions in honour of the Virgin of Orreaga, a Gothic image housed in the main church.

The legend of the Virgin and her appearance involves a shepherd boy and a roe deer. The shepherd heard singing one day beside some rocks. He approached and saw a roe deer with luminous antlers foraging in the earth. At that moment, the image appeared. The same basic narrative structure is repeated for other manifestations throughout the Pyrenees; shepherds and deer in the woods, where these animals, besides their importance within Christian symbolism, are of great significance.

Otsagabia: Large, fortified church dedicated to San Juan Evangelista. Overlooking the village, the solid block of its nave and its chamfered tower provide the main feature of the silhouette of the village. It is a monumental work built over different epochs. There are remains of a mediaeval church from around 1200 on the epistle wall. These remains now appear in the form of a crypt saving the slope on which the considerably larger, current church was built in the first half of the XVI century. The sacristy and the chapel in the northeast are from the XVII century.
It still preserves the wooden-slat roof typical of buildings in the Valley of Salazar until the beginning of the XX century.
Its interior protects splendid, Renaissance reredos.

Isaba: XVI-century Church of San Cipriano, with fortress-like airs and a curious reddish roof. It has an attractive, main reredos in the Plateresque style, a beautiful Baroque organ dating from 1751 and a carving of the Virgin of Idoya with Child.

Arce: The Church of the Purísima Concepción in Arce is an outstanding example of XII-century rural Romanesque and has been declared a Monument of Cultural Interest. It was built by the lords of Arce at the site where meetings of the Valley used to be held, at a distance from the villages, during the golden age of the Kingdom of Navarre on the peninsula. Two centuries earlier, Sancho the Great had managed to definitively assign the route of the Pilgrims’ Road to Santiago through Navarre, which encouraged strong spiritual and moral sentiment in the face of the Moorish influence and favoured the arrival of European currents.

Artaiz: the Church of San Martin de Tours is located on a small hill in this small village in the Valley of Unciti. The iconographic value of the sculpture on its doorway and eave make it a jewel in the crown of rural Navarrese Romanesque. It was built over the XII and XIII centuries and nobody knows who commissioned it. It does not feature among the dependencies of the Hospital of Roncesvalles or the Monastery of Leire and the outstanding quality of the craftsmanship could not possibly have been paid for by the sparse, local population. This leads scholars to believe that Artaiz belonged to an estate (possible that of the Almoravid, a rich, Navarrese family). Together with the Chapels of San Pedro de Echano in Oloriz and Cristo de Catalain in Garinoain, the Monastery de Azuelo and the parish churches in Olleta and Arce, it belongs to the circle of influence of Loarre.
The church underwent restoration in 1958.

Abaurrepea-Abaurrea Baja: : XV-century Gothic church dedicated to San Martin de Tours. Made of stone, it consists of a single nave divided into three sections with a polygonal apse. The balustrade of the stairway leading to the choir and the choir itself are worthy of highlight. This church conserves the only worked railing in Aezkoa, where altars used to be separated from the worshippers.

Aurizberri-Espinal: Modern church built in 1961 in honour of San Bartolome.
