Santa Katalina hermitage is a hermitage located in the Mundaka municipality of Bizkaia. It is located on the peninsula of the same name, in an area of u200bu200bgreat geostrategic value, as it has an excellent view and was once an excellent defense of the sea access area of u200bu200bUrdaibai. On the other hand, Izaro and Ogoño can be seen more unfavorably.

The current hermitage dates back to 1879, but since the Middle Ages it has also been a warehouse, a hospital during plagues and a defense fortress.

Although the basilica was damaged by sieges and underwent numerous reconstructions as a result, the building has been able to maintain its original transitional style between Gothic and Renaissance. On the other hand, in terms of history, the wall that surrounds the building should also be mentioned, since this also dates back to the time when the building was rebuilt.

Today, it is one of the main tourist centers of this municipality, and this is how it is stated on the municipal website. Furthermore, every year on November 25, the people of Munda celebrate the feast of Santa Catalina around the building and inside.
