Artajona

The oldest traces of human presence around Artajona are megalithic. The municipality contains the southernmost group of dolmens in Navarra, two large gallery tombs, Portillo de Enériz and La Mina de Farangortea, set within mounds over 20 metres across and 2.5 metres high. They don't fit neatly into standard megalithic categories, sitting somewhere between covered-gallery tombs and corridor tombs.

Chalcolithic, Bronze Age, and Iron Age sites are scattered across the surrounding area, and an Iron Age settlement at Guencelaya yielded a decorated stone altar with a bull's head. Archaeological work carried out between November 2007 and February 2008, commissioned by the Government of Navarra during restoration of the walled enclosure, confirmed a Roman settlement from the early imperial period, after which the site appears to have been abandoned until the central medieval centuries. Artajona also played a significant role in the history of agricultural cooperation in Navarra, founding a series of cooperatives from 1904 onward covering rural credit, wine, olive pressing, threshing, and food preservation.

During the Spanish Civil War, the town became known for sending 775 of its 800 available men to fight as Carlist volunteer infantry.

The dominant feature of Artajona is El Cerco, a medieval walled enclosure containing the Gothic church of San Saturnino, which has two bells still rung on feast days. The town also has the church of San Pedro, the hermitage of Nuestra Señora de Jerusalén, which holds a carving of the Virgin, and the hermitage of San Bartolomé. In the old town, a cobbled street and the Arco de Mayora survive from the medieval layout.

Outside the walls, a stone fountain called the Fuente de los Caños, built in the form of an arch with two water spouts and small basins, still stands. The surrounding countryside holds three dolmens: Dorre, La Mina, and Portillo de Enériz.
