One of the most important collections of musical organs is found in the historic Basque province of Gipuzkoa (the Basque Country, Spain). Amongst approximately 150 instruments that make up this class of musical heritage in Gipuzkoa, special mention should go to the magnificent Spanish baroque organ of Ataun, built by Lorenzo de Arrázola in 1761, as well as the splendid collection of French romantic organs, led by Aristide Cavaillé-Coll who installed 14 instruments of all kinds and sizes in this province between 1861 and 1898. To these have to be added those built by other French organ-makers such as the Stoltz-frères (Paris), Mutin, Merklin/Gutschenritter, Puget, Didier, etc.
Particular mention should also be made of a beautiful instrument by the German organ maker, Walcker, installed in 1914. To this extraordinary current collection of organs in the territory of Gipuzkoa the instruments of romantic influence have to be added; these were created towards the end of the XIX century by organ makers of Basque origin and closely tied to the Basque Country, such as Aquilino Amezua, Eleizgaray & Cia., Amezua & Cia., Lope Alberdi, Melcher and Dourte, amongst others. The process of installation of the organs of romantic influence came to an end in 1940. That was when the Organería Española Sociedad Anónima was established in Azpeitia (Gipuzkoa), the company that installed, in the cathedral of the Buen Pastor (Good Shepherd) in San Sebastián in 1953, the largest neoclassical organ in Spain with five manuals and one pedalboard and 125 stops.
