Created in 1988 by Artur Blasco i Giné, this is one of the few examples of a museum in the world dedicated entirely to the accordion instrument. With instruments dating back to the forties of the nineteenth century to the present day, this museum helps to better understand the relationship of the instrument with the world of popular and traditional culture of the Pyrenees of Lleida in a town where , precisely, every year the Meeting of Accordionists of Arsèguel is celebrated.
