Cape Matxitxako, located in Bermeo, is a prominent headland on the Basque coast, marking the northernmost point of Bizkaia. Its strategic maritime location has made it a significant navigational point for centuries. The cape is also a notable natural landmark, offering dramatic coastal scenery and diverse ecosystems. Its name, derived from the Basque word matxete (axe), possibly refers to the shape of the cape.

There are two lighthouses in Matxitxako: The first, a smaller structure, was built in the mid-19th century but due to its insufficient height and visibility, a new, more modern lighthouse was constructed in the early 20th century. The new structure, which is still in operation today, features a powerful light that can be seen from over 20 nautical miles away, ensuring the safety of vessels traveling through the area.

The location is also known because during the Spanish Civil War, the waters off the cape were the setting for the Battle of Matxitxako in 1937, a naval conflict between the Basque auxiliary navy and Francoist forces.

While the lighthouse interior is not typically open to the public, there are some information panels and a viewpoint area in the outside of the old ligthouse. The nearby San Juan de Gaztelugatxe can easily be seen from the lookout.
