Near Artajona, atop a small summit where a settlement existed during the Bronze Age, stand the dolmens “Portillo de Enériz” and “Mina de Farangortea”, one of the most significant examples of the megalithic culture in Navarre.

The Artajona dolmens are a unique example of megalithic culture in Navarre. While dolmens are numerous in the mountainous areas, where they are generally small in size, these are the southernmost in Navarre. Their large proportions bear strong similarities to those found in La Rioja and Southern Araba, such as the Dolmen of El Alto de la Huesera or Dolmen of San Martin.

These two dolmens belong to the “corridor” type and are composed of large stones (megaliths). They feature a dividing slab and a double chamber and are built on burial mounds measuring 20 meters in diameter and 2.5 meters in height. Neither of the two had a stone roof; instead, they were covered with branches and soil. Around these dolmens, archaeologists discovered necklace beads, arrowheads, copper awls, buttons, pottery, and axes, which are now displayed in the Museum of Navarre.

Specifically, “Portillo de Enériz” is a megalith consisting of two distinct parts: the burial chamber, where the deceased were placed, made up of nine large vertical slabs; and the corridor, which consists of six smaller slabs. The “Mina de Farangortea” dolmen has the same structure but is smaller in size. Additionally, the central slab at the back is perforated to allow access.

Well signposted, they can be accessed via a path that starts behind the Artajona cemetery. Alternatively, visitors can drive directly to the “Portillo de Enériz” dolmen. After parking in an area with informational panels and wooden benches and walking 40 meters, you will reach the “Portillo de Enériz” dolmen, while the “Mina de Farangortea” dolmen is 850 meters away along a well-marked path.
