Arbaizenea is a country house built in 1881 that presides over an environment of two hectares of green and wooded land. It was one of the jewels of the Duchess of Alba, where she went every year during the summer.

After the death of Cayetana Fitz James Stuart in 2014, the palace and its extensive gardens were inherited by Cayetano Martínez de Irujo. The aristocrat wants to make a financial return on a mansion that remains closed and locked for most of the year.
