It is located in the historic centre of Azpeitia, next to the Parish Church of San Sebastián de Soreasu.

It was built by Juan de Antxieta, musician of the Catholic Monarchs, circa 1507. The most prominent building is the façade, a prototype of Mudejar style. It is built in several stages, alternating the building materials, stone on the ground floor and brick for the rest.

Like in other tower-houses of the valley, that of Balda was demolished in part by order of Enrique IV, removing the defensive aspect of the 13th century tower. This house was one of the Gamboinos centres during the Struggle for Sides.But in addition, Marina de Licona, the mother of San Ignacio lived in this house before marrying Mr. Beltrán de Loyola in 1467. It conserves a small chapel in honour of the Holy Founder of the Jesuits.

On the old plot of Sancho Sánchez de Zuazola his grandson Pedro, who became the Treasurer General of Emperor Carlos V, built this unique Mudejar building circa 1515.
From 1677 it went into the hands of the Counts of Garciez and it lost its original splendour.
