Charles Mutin, on acquiring the Cavaillé-Coll business in 1898, did so keeping its prestigious, internationally-renowned name. This fact has, at times, given rise to confusion regarding the attribution of certain instruments to Aristide Cavaillé-Coll, when, in fact, they were the work of his successor, Charles Mutin.
It was a donation of the Muñoa family that enabled its inauguration on 28 December 1902. Its cost was 32,000 francs. It is a beautiful and interesting, medium-sized instrument which is also in its original state. Special mention should be made of the number of programmable stops (indicated with asterisks), with an original and characteristic system by Charles Mutin. It was restored by Azpiazu-Altuna (Azpeitia) in 1978.
In 2013 an important restauration was undertaken in which all the fundamental parts of the organ were maintained. This work was carried out by the organ builders J. Sergio del Campo and Alejandro Turanzas.
