"Las Eretas" Museum and Archaeological Site

Museums / Archaeological


See all the photos


This museum located next to the archaeological site of Las Eretas is the ideal starting point before visiting the conserved ruins, as it helps us to understand what life was like in that fortified settlement at the end of the 7th century with its walls and towers.

An open-plan building, 23 metres long by 5 metres wide, takes us chronologically from the end of the Bronze and Iron Ages until the Romanisation of the territory.

The "Las Eretas" site is located on the right-hand bank of the river Arga. On arrival, you will find an esplanade encompassing a perimeter of 550 square metres which reveals the urban layout of the settlement, marked out by an exterior wall and towers. The site is equipped with information panels and wooden walkways to guide you without coming into contact with the ground.

The protohistoric site of Las Eretas was discovered in 1991 and the excavation work that took place between 1993 and 1996 revealed part of the urban layout of a settlement consisting of a street and a kind of central square. On the sides of the square, and built in to the walls, were rectangular homes with roofs covered in vegetation that measured between 36 and 72 square metres.

One of the most important elements of the site is the wall, a 10-metre stretch of which has been rebuilt. It is 5 metres high, and on it is a reconstructed house built in limestone with a straw or reed roof, measuring 67 square metres. Visits can be made to this house. Inside the house, which is artificially illuminated, you can discover some of the typical furnishings of the era such as benches, ovens, fireplaces and meat stores.

A stroll round the village also reveals one of the towers that once existed here. It is 5 metres high and the same building techniques were followed for its reconstruction as for the towers built 2,500 years ago, using identical materials.

To understand this era of history, an essential visit is to the museum of Las Eretas. An open-plan building, 23 metres long by 5 metres wide, takes us chronologically from the end of the Bronze and Iron Ages until the Romanisation of the territory.

The visit starts with a 15-minute audiovisual. For the children, there is an original presentation consisting of 15 pages of drawings of what life was like in Las Eretas. They show a 21st-century child dreaming about Arbulo, a small boy from 2,500 years ago who shows them his village, house, and family and explains how people lived in that fortified hamlet of artisans and farm workers.

The visit continues through twelve thematic areas that explain the way of life in the Iron Age through original pieces and reproductions such as ceramic containers, polished axes or arrow tips; large murals such as the one that graphically reproduces a child's burial; informative panels; two scale models; the recreation of a site being excavated and a monographic audiovisual loop lasting 5 minutes in which the settlement of Las Eretas is recreated virtually on real images of its ruins. Basically, it is a learning centre for all ages and an excellent entry point to the ruins of Las Eretas.
