Although the current hermitage, located in the Isla Bekoa neighborhood of Gautegiz Arteaga, was built in the 16th century, its head features an inlaid window of clear pre-Romanesque origin from the mid-10th to the 11th century.

The municipality of Gautegiz-Arteaga preserves the only tidal flour mill that once existed on the Urdaibai estuary: the Ozollo Errota tidal mill. Furthermore, the Arteaga mill is the best preserved and the only one that retains most of its facilities. The mill was built around 1683, in the marshland of Laida Beach, in the Kanala area. An area of the marsh was used for its construction, enclosing it with walls, and it was fed by the dam in the rear reservoir. In addition to the milling house, where the drive wheels were installed, the mill has a building at the lowest point of the reservoir. This is a house located on the edge of the estuary, above the same water inlet and outlet. Therefore, the Ozollo Errota tidal mill is the most notable heritage structure in Urdaibai. The mill ceased to operate in the early decades of the 20th century and has been privately owned for several years.
