The Algorri Interpretation Centre in Zumaia, which takes its name from the site of the K/T boundary in the town (geologic strata that marks the fifth large-scale mass extinction on a global scale) provides an enjoyable experience for visitors, providing information about the nature of this coastline, including the formation of flysch.
Mutriku cliffs, formed by black flysch strata, are very rich in fossils that date back over 100 million years. As a result of the many long years of work and recovery by local man Jesus Maria Narvaez, an extensive collection of samples have been built up and are now on public display in the Nautilus Centre.
A cultura space created by the Basque painter Ignacio Zuloaga to work and exhibit the works of art he himself painted and collectioned during his lifetime. You can visit also the Santiago hermitage, on the Coastal route of the "Camino del Norte", the historical collection and the painter's studio-workshop.
