The Castro de Henaio, located in the municipality of Alegría-Dulantzi (Álava), is an important archaeological site in the Basque Country, offering valuable insight into the region’s ancient settlements. This fortified settlement, or castro, dates back to the Iron Age, with evidence of occupation from the 6th to the 2nd century BCE.

Strategically positioned on an elevated area, the site provided natural defense and control over the surrounding territory. Archaeological excavations have revealed remains of defensive walls, dwellings, and other structures, indicating a well-organized settlement. The presence of pottery, tools, and metal artifacts suggests an economy based on agriculture, livestock, and trade.

The Castro de Henaio is significant for understanding the early societies that inhabited the region before the Romanization of the Iberian Peninsula. The findings suggest cultural and commercial exchanges with neighboring communities, reflecting a society with complex social and economic structures.

The visit begins at the Interpretation Center after leaving the car at the exit of Alegría-Dulantzi and taking a short walk on foot. Several panels explain the way of life of the inhabitants of the castro, and two life-size houses showcase the construction and interior environment of the settlement’s dwellings, based on data gathered from archaeological studies.

Outside, visitors can follow a short and simple route along the hill, marked with posts and informational panels, to observe the reconstruction of the settlement’s walls and the terraces that extended across the slope. These terraces helped level the terrain, making it easier to build houses.

The Castro de Henaio is a key site for those interested in the ancient history of the Basque Country, offering a glimpse into the life of its early inhabitants and the evolution of settlements before the arrival of Roman influence.
