Erandio has a rich history that dates back to the early medieval period, although the area was likely inhabited long before due to its strategic location along the Nervión River. It grew primarily as a fishing and agricultural village before becoming more industrialized during the 19th and 20th centuries. Erandio was significantly influenced by its proximity to Bilbao, which was a major industrial hub. Despite modern developments, the town has maintained much of its traditional Basque character, with a focus on community, language, and culture.
The Basque identity is strongly preserved in Erandio, and many of the town’s residents speak both Spanish and Euskara (the Basque language). Local festivals such as San Agustín and San Pedro, held in summer, are important cultural events, celebrating both religious and historical traditions with music, dance, and food. These festivals provide an opportunity for visitors to experience authentic Basque customs and participate in lively communal events.
Erandio’s cultural heritage is also reflected in its architecture and local customs. Visitors can explore historical churches, old town squares, and attend traditional Basque sports events, such as pelota vasca (a Basque ball game), making it a culturally enriching destination for tourists and event organizers alike.
