The first stone was set on April 2008. The museum building structure was built in about an hour, as a result of the use of a pioneer technique for cultural buildings in Spain.[7] This way, it took about an hour to set up the whole structure. Then both the "Multipurpose building" and the "Auditorium" were constructed. The materials used were mainly concrete and glass. Also during this time the basis of the "Tower" was started, but it was not until the structures of other buildings were almost finished that the works on the Tower were visible. An underground car park was added. The "Open Square" was covered in white concrete. The sides of the Auditorium were painted in yellow, creating a contrast with the dominant white colour. On one of the sides of this building, a ceramic art work, designed by Niemeyer, represents the outline of a woman resting. The stage door was painted in red. This door can be open to the square, so that shows can take part inside or outside the building
