In Ormaiztegi we find the Iriarte-Erdikoa House which was home to the Carlist General, Tomas Zumalakarregui. It is an 18th century farmhouse that after remodelling has been converted into a Museum. Dedicated to the Carlist general and his era, this museum keeps, apart from personal, military, and decorative articles and correspondence, very significant documentation from the Basque history of the 18th and 19th centuries.
