Once inside the Hall, visitors access the Atrium, the real heart of the Museum and one of the signature traits of Frank Gehry's architectural design. With curved volumes and large glass curtain walls that connect the inside and the outside, the Atrium is an ample space flooded with light and covered by a great skylight. The three levels of the building are organized around the Atrium and are connected by means of curved walkways, titanium and glass elevators, and staircases. Also an exhibition space, the Atrium functions as an axis for the 20 galleries, some orthogonally shaped and with classical proportions and others with organic, irregular lines. The play with different volumes and perspectives generates indoor spaces where visitors do not feel overwhelmed. Such variety has demonstrated its enormous versatility in the expert hands of curators and exhibition designers who have found the ideal atmosphere to present both large format works in contemporary mediums and smaller or more intimate shows.
In addition to the gallery space and a separate office building, the Museum has a visitor orientation room, Zero Espazioa; an auditorium seating 300; a store/bookstore; a cafeteria; and two restaurants: a bistro and a one Michelin star haute cuisine restaurant.
