Zaldibar can be translated from Basque as "horse valley", from zaldi and ibar. The coat of arms of the town then includes a horse. Zaldívar is the name in Spanish. However, the town was named Zaldua or Zaldúa until 1932. Zaldua is then translated from Basque to Spanish as "el soto", which might be referred to a sotobosque, Spanish word for understory. "Valley of the Soto" is then another possible origin of the current name. Currently, Zaldua is considered an archaism and it is not used, being since 1980 Zaldibar the official name of the municipality.
History
The elizate of Zaldua, today Zaldibar, was part of the ancient merindad of Durango and had voice and right to vote in the Juntas of Guerendiaga, where it occupied the seat number seven. As it is common with the elizates, the original date of founding is unknown. Tradition goes that the Navarre kingSancho II of Pamplona lived ten years in one of the towers of Zaldibar as a prisoner. The owners of the afore-mentioned tower controlled several territories of what today is Zaldibar. There are historical data that places the construction of the San Andreschurch inthe 13th century. The church was reconstructed in 1778 from previous damage. Zaldibar harbours an industrial dumping landfill managed by the private company VerterRecycling. In early February 2020, a landslide in the landfill blocked the main Bilbao-San Sebastián motorway, bringing about a major environmental disaster. Two operators remained missing under toxic mud for several weeks.
