Urzainqui: Esca Valley and Historic Architecture

The Esca River flows through Urzainqui at the foot of the Santa Bárbara and Arrigorrieta mountain ranges. The shape of the valley also changes: it widens in the more easily eroded flysch, while narrowing into a gorge where it cuts through limestone outcrops. The widening and narrow sections reveal two different sides of the same landscape.

River Landscape and Local History

Urzainqui’s settlement pattern preserves the influence of forestry and timber transport around the old river port. The Esca is therefore not only a defining feature of the landscape; the former river port also links the town’s history to the transport of timber. The landscape and the settlement pattern tell, in different ways, of the relationship between the town and the river.

The geological sequence offers another way to understand the landscape: where the Esca valley broadens in the flysch, it narrows into a gorge at the limestone outcrops. The changing shape of the valley is a distinctive feature of the area, separate from the historic buildings and hiking trails as a focus in its own right.

Churches and Historic Architecture

The Church of San Martín de Tours brings together several building phases. Its main structure is an early proto-Gothic building from the beginning of the 13th century. A portal was added later, in the 16th century, and the side aisles were probably added during the Baroque period. The church therefore cannot be assigned to a single period: the main structure, portal, and side aisles represent different stages in its building history.

The furnishings of San Martín de Tours include a Gothic reliquary, a Renaissance processional cross, and a 16th-century Ecce Homo painting with Flemish influence. These works of art add examples of different styles and forms to the architectural traces of different periods. Anyone wishing to learn about Urzainqui’s history will find both medieval and later influences here.

The Chapel of Nuestra Señora de San Salvador was formerly Urzainqui’s parish church. It is Gothic in origin and was restored during the Baroque period. The chapel houses a 14th-century Gothic statue of the Virgin Mary. The altarpiece also has its own art-historical significance: it was Francisco Pejón’s first documented work in Roncal and Navarre. The contract for the altarpiece was signed on October 8, 1737.

Other historic buildings include the ruins of Urzainqui Tower. The structure dates from the 16th century; its large pointed-arch portal and a coat of arms bearing a Christogram are specific details of its recorded appearance. Together with the two religious buildings, the tower ruins show how religious art and civil architectural history can be viewed as distinct aspects of the town.

Hiking Trails Starting and Ending in Urzainqui

The SL Camino de la Boca hiking trail begins at the Chapel of Nuestra Señora de San Salvador. From there, it descends to the NA-137 road and then returns to Urzainqui. Its route thus connects a named starting point with the stretch to the road and back to town.

The SL-NA 77 Isaba–Urzainqui is 5.3 kilometers long, has an elevation difference of 250 meters, and a stated walking time of 1 hour 30 minutes. The trail ends in Urzainqui. Check current trail conditions before setting out.

The historic route of the SL-NA 77 follows an old connecting path between Isaba and Urzainqui. It passes through wooded slopes, high ground, and ravines; some of the original sections have been affected by forest roads. The descent to Urzainqui follows the old Camino de Aizaritu, which was once an important access route to the fields at higher elevations. The two trails therefore differ in more than just their routes: the SL-NA 77 also offers a connection to the historic link between the towns and the former agricultural use of the descent.
