Palacio de Arbaizenea

Palacio de Arbaizenea is a palace in San Sebastián situated within a park setting, displaying residential architecture with elements of a traditional house in the northwestern area of the city. The estate includes both the main buildings and the surrounding green spaces.

The palace passed into the ownership of the House of Alba through a marriage alliance between the Arbaizenea family and the House of Sotomayor. This dynastic connection anchored the estate within one of the peninsula's most prominent noble families.

The palace displays features of traditional Basque architecture, with details reflecting the local building style of the region. It maintains this distinctive appearance to this day.

The grounds are partially accessible to the public after a 2006 agreement with San Sebastián City Council opened about 2 hectares of the private park for public use. Visitors can explore the outer areas, but should be aware that some parts of the estate may not be open to enter.

The estate sits close to other noble residences like Palacio de Ayete, making this area a special hub of local nobility. The cluster of these estates demonstrates the historical significance of this northwestern zone for the city's wealthy families.
