This village on the banks of the River Esca lies in the foothills of the Sierras of Santa Barbara and Arrigorrieta.
The distribution of the houses in Urzainqui clearly reflects the influence of the timber trade in the valley, surrounding, as they do, an old river quay.
Of particular note are the Chapel of San Salvador on the main road and the Church of San Martín, together with civil constructions, such as a tower-house from the 15th century.
Church of San Martín de Tours
The main core of this Baroque church is a proto-Gothic construction from the beginning of the 13th century, to which was added a portico in the 16th century and side naves, probably in the Baroque. The ceiling of the central nave consists of rib vaulting, the side naves have groin vaulting and the chancel, a sexpartite vault. The choir stands in the last section of the central nave. From the outside, the main features include the bell tower, typical of Mediaeval churches from the time, and a portico with a tierceron vault. Inside, the most important silverware includes a Gothic reliquary with the hallmark of the Pamplona borough of San Cernin and a processional cross from the Renaissance. Mention should also be made of the 16th-century, Flemish-style, panel painting of the Ecce Homo.
Chapel of Nuestra Señora de San Salvador
The chapel was an old Parish church and has the same style and chronology as the church; built in the Gothic style and restored in the Baroque style. The building has a nave in three sections and a square chancel with rib vaulting. The main features inside are a 14th-century Gothic carving of the Virgin and a Christ on the cross reminiscent of the Flemish tradition.
A Renaissance cross from 1597 with a carving of the Virgin. The cross consists of four stone steps with diamond-shaped decoration, a fluted shaft and a complex capital on which the remains of the cross with intricate hollowed embellishments sit. The Christ on the cross on the face belongs to the expressivist tradition and there is a Virgin on cherubim on the back.
Built to reflect local architectural tendencies and reconstructed in 1984. The building is rectangular and has a ground and upper floor.
Ruins of the Urzainqui Tower
16th-century construction with a large pointed doorway with substantial voussoirs and a shield with a Christian symbol on the keystone.
Casa Krutxaga and Casa Melikotx
Located in the castle district, or Ingruñía; the trabeated doorway and a Neoclassical coat of arms on the balcony of the main floor are the most notable features.
