Matxitxako Lighthouse, Coastal lighthouse in Bermeo, Spain

Matxitxako Lighthouse stands on Cape Matxitxako, about 10 km northwest of Bermeo. The 1909 tower is octagonal, built of stone with a gallery and lantern, and adjoins the front of a two-storey white-painted keepers' house. Its first-order Fresnel lens gives a white flash every seven seconds, visible up to 48 km.

The first lighthouse opened in 1852 on the cape's point, 64 m above the sea, with a sixth-order rotating lens and a white flash every four seconds. In 1909 a new tower was built 100 m from the old one, with a first-order Fresnel lens visible for 48 km. It was electrified in 1937, gained one of Spain's first radio beacons in 1926, and a fog siren was added in 1963.

The lighthouse marks the cape the sources call the most dangerous on the Basque coast, and its keepers give guided tours when their duties allow. In 1926 it received one of Spain's first radio beacons, and since 1963 a siren in the old tower sounds on foggy days. A bird and cetacean observatory is attached to the lighthouse.

The lighthouse sits on a headland with several viewpoints from which visitors can photograph and observe it from different angles. It is advisable to wear sturdy footwear, as the paths to the viewpoints are rocky and uneven.

In 1926 the lighthouse received one of Spain's first radio beacons, guiding ships by radio signal in fog long before radar. The old tower, replaced in 1909, later housed the fog siren installed in 1963. The site also holds a bird and cetacean observatory, run from the lighthouse itself.
