Visit to Arrietakua Palace:

The Arrietakua Palace, is a beautiful palace dating back to the 18th century, located in the heart of the Old Quarter of Mutriku, transporting you back in time to get a feel for the history and accomplishments of the seafarers, navigators and other great personalities of its past.

Built by Admiral Antonio de Gaztañeta, a renowned naval builder, between the 17th and 18th centuries, it is the birthplace of Brigadier Cosme Damián Churruca, a great scientist and hero of the Battle of Trafalgar. Currently, it is the house of Count of Mutriku, José María de Areilza y Carvajal.

It is a unique and remarkable experience, since the palace has been preserved as it was in the eighteenth century, safekeeping the belongings of the Gaztañeta and the Churruca families until today.

This palace is a good example of the connection that this town has with the sea and it is one of the jewels of the maritime heritage of the Basque Coast.
