Standing on a hill beside the Urola river, alongside what was once the Royal Way, Zestoa was in the Middle Ages a town with the mission to facilitate communications and relations. Despite the local way of life being largely dedicated to agriculture and livestock breeding, and later industry, this is a town which has always maintained an enormously important services sector with its sights set on meeting the challenges of the 21st century.

Although people have lived in the area of Zestoa since the Palaeolithic Era, the name of Zestoa found its way into history with the royal charter granted by the King of Castile, John I. The town was founded and fortified in the Middle Ages, conditioned by the feuds between nobles. However, several factors meant that it progressed differently from other neighbouring towns. The thermal waters found in the mid-18th century brought the start of a new era. In addition to health tourism, lignite extraction from the Ertxina mines and the cement industry also had important influence on Zestoa's long history.

Music, cinema, literature, painting, dance… For a small town like this you'll find a wide-ranging variety of cultural expressions, whether at popular level or professionally through the people dedicated to them.
