The auditorium is recognizable by its curvy, concrete shell exterior.
‘Most of the richly differentiated volumes of this intricate compact composition were derived from relatively simple geometrical shapes or operations. For example, the shape of the roof is defined by two intersecting cone segments. The shape of the 50-meter hugh symmetrical inner shell of the concert hall was generated by rotating a curve to describe an ellipse: a wedge if approximately 15 degrees was removed from the center of this body so that its two segments form a pronounced ridge that supports the sweep of the roof.’
The main feature of the building is the huge, symmetrical, wave-like curve that arches 58 meters over the auditorium. The narrowing bow ends at a point and implies movement; typical of Calatrava. The majority of the building is made of concrete giving the exterior structure more dominance. However, smaller areas throughout the plinth of the building are made from the local volcanic rock, basalt. The plinth actually houses several technical facilities as well as the change rooms. On the side of the building are two wide 50 meter arches which serve as the entrance for performing artists. The main entrance is on the raised plaza under the hanging curve. A interesting thing to note is the relationship between the interior and exterior; with such a grand exterior, its amazing how such magnificent interior spaces exist within.
