The Parish priest of Agüero Luis Galindo Bisquer is the artificer of the only organ museum known all around the world as he assures in his book titled "the historical organ in the province and diocese in Huesca". In the last fifteen years he has rescued some organ pieces from extinction since the beginning of XVI century. He was an enthusiast of valuable and abandoned things. This priest has got thanks to Jaca bishopric, who is the owner of the museum that Aragón has in this area a very important patrimony opened to the public.
     Placed in the abbey house, the objects and pieces from different organs, each one with its informative report are distributed in four rooms. You can make the visit in the museum with the help of a magnetophone, which reproduces in a tape the explanations about it. In the entrance court you can find a typical caddie, a stone step, a picture with a pyrography drawing of a seven tubes organ and at the foot we can find a lovely stone which supports a decorative plant.
     On the court's left a door, which leads to the first room, is opened. The visitor will be able to contemplate a bread flute which the people in the village used for their songs and dancing. They are seven small joined pipes cut in a diagonal shape, which give a different aspect from the others.
      In a very big vitrified table with inside illumination different elements, which any organ may have, are placed. These elements may be some tubes, box tree wooden or ivory keys, or made with both materials, several proper mechanisms of the organ: some valves, small mills, knobs with or without an indication of their tone, pulleys, springs and a wooden tambourine with some orifices of different diameters which supports the tubes firstly the superior ones and then the minor ones.
      Many of the tubes are shown as they were rescued l from abandon, worn out due to rats, which gnawed at metal, or due to the harm they were given. They were also caked or bossed or with tin in a very bad condition due to the weather. These tubes are sometimes made of wood, covered with paper and there are also sometimes some musical letters or writing. There are some trumpets, tuning keys, tongues, and some pieces, which show the fabrication process of a tube. A secret, two pedals and some pieces belonging to the lowest part of an organ are placed along the wall. These kinds of pieces may be some pedal, organ tubes, scales and canon tubes that don't work, so they were only built as an adornment..
     In the second room, illuminated with natural light, we can find a showcase with some lithographies dedicated to Agüero's museum. On its walls some nasards, comets, little birds and two beautiful angels, which support two trumpets, are hanged. They are romantic tubes, some pieces with a shape of a banderol and some ornamental ones. The sample has also dates of some historical pieces and concrete organ makers and a very beautiful collection of postcards with copies of Spanish and foreign organs. In the third room we can find a complete organ built in 1972 by Luis Galindo. It is an ancient imitation where the tubes at sight to be able to watch them better. The secret is an ancient one. Referring to the disposition of the organ it has a wooden box tree key. The visitors can listen to the different registers and see its functioning. For this reason the organ has an inside illumination.
      The room where Mosén Louis' organ is placed has got a wonderful carving made of ancient wood of Saint Cecilia who was musicians' Patron saint. This carving was made as ornamentation in the organ museum by Antonio Suils Pérez who came from Anzánigo. It has a small pyrography picture with the organist's pray.
- Sir! My heart is in my hands. Let's them serve always to praise you. If the music they give recreate or elevate listeners, do not let it serve to make me vain. It should serve to thank you for the great gift to be able to express what only the man's depth can say. Amen.
     Descending to the ground floor can finish the visit to the museum where you can admire an organ box-façade. On the upper floor one of the rooms is dedicated to keep organ pieces.
     Louis Galindo Bisquer assures that there were a lot of visitors who went to Agüero to visit the museum a long time ago. 'However I do not know the reason why fewer visitors come to visit it at preset. Perhaps it may be because the museum is located a little out of the way from the road and the visitor has to turn around it to reach it'. Meditating on the organ Galindo has laudable words for the ones called "tuberos". 'In Spain, as I can know one two men have this job. One of them is called José Jiménez Rusiñol and the other one is called Vinancio Rodríguez Rodríguez. In the workshop they have in "El Buen Pastor" in Barcelona the make the tubes destined to those big or small harmonies firms destined to Sacred cult or to the Spirit fascination in sacred concerts. They are artisans who use plumb, or tin to work but they rarely use zinc or copper'.
     Works made by these tuberos have made a great impression in Luna, Loarre, Pertusa, Hecho and in the organ of M.M. Benedictinas' church in Jaca, according to the book titled "The historical organ in Huesca province and Jaca diocese'.
