Pau Casals Auditorium is situated in the maritime area of Sant Salvador, opposite to Pau Casals Museum. It has been built in a modern and agile framework, in order to fulfill its basic function, to be a concert hall. It was opened on the 6th of June 1981 thanks to the effort and good will of different institutions to save all the difficulties at the moment who made possible to carry out Jordi Bonet Armengol's project. This architect wrote: "The whole building reminds me an awning and it shows clearly the functional nature of a concert hall. The inward appearance will pretend to be a boat keel, showing its ribcage. This will allow a reflector or absorbent surface that will break the sound and will correct the reverberation time till the optimum demanded for the concert halls". It has to be emphasized the lighting of the room and the stained glass windows at the back of the stage, made by the painter Vila Grau and the glazier Granell. The concert hall has a capacity of four hundred people and it's equipped with air conditioned and heating. The hall is used for receptions and exhibitions, and it has spacious rooms that as well as giving many possibilities it grants a great versatility of functions.
