It is said that its previous name was “Ibai Baso” “river and forest” which correctly defines two of the most characteristic elements of the area, water and stone. These elements are of great importance in this small municipality where its history is linked to forges, mills, dams and bridges.

Gizaburuaga is a symbol of prehistoric environments in Bizkaia. In its caves we can fiind prehistoric settlements, mythology and history.

There are currently no forges, but characteristic elements from the past can be seen along the river. The most important of these is Bengolea. In the 17th century it was the most important forge in Bizkaia designed by Pedro Bernardo Villareal de Berriz, an icon of the practical application of modern science.

In this same area is located the Oibar hermitage and the cave with the same name. Today, the neighbourhood is also known as the industrial area of Okamika, created by the municipalities of the valley.

Rest area: Errota-Zahar

This is the place where the mill used to be, now known as “Errotazar”, although there are not many signs of it. It is an area where you can relax, watch the river and the old dam, now submerged. On the panel you can learn how the mill works and its history.
