The Celtiberian Pond of Barbacana is a remarkable archaeological structure located in the town of Laguardia, in the province of Álava. Dating back to the 1st century BCE, it is one of the best-preserved hydraulic constructions from the Celtiberian period in the Iberian Peninsula.

This pond was excavated into the rock and designed to store and manage water, an essential resource for the local population. With a capacity of approximately 300.000 liters, it was used to supply water for both domestic and agricultural purposes. The careful construction, including waterproofing techniques, demonstrates the advanced engineering knowledge of the Berones, the Celtiberian tribe that inhabited the area before the Roman conquest.

The structure was discovered in the 20th century during restoration work, revealing its impressive dimensions and functionality. Nearby, remnants of a Celtiberian settlement have also been found, providing further evidence of the importance of water management in ancient societies.

Today, the Celtiberian Pond of Barbacana is protected and accessible to visitors, with explanatory panels detailing its history and significance. It is an important site for understanding the daily life and technological advancements of the pre-Roman inhabitants of the region. Its location, within the historic center of Laguardia, allows visitors to combine its exploration with other cultural and historical attractions of the town.
