The romantic organ of the church of Zumaia, San Pedro Apostól, was built in 1890 by the famous organbuilders Stoltz-Frères from Paris, France.

It has only 15 stops on two manuals and pedal, but it sounds really powerful however. It is the smallest of the three prestigeous Stoltz-Frères organs in the Basque Country (Tolosa and Bergara are the bigger sisters).
