Guggenheim Museum Bilbao

The Guggenheim Museum Bilbao opened on 18 October 1997 on the south bank of the Nervion River in the Abandoibarra district of Bilbao, Basque Country. Designed by the American architect Frank O. Gehry, the building is widely regarded as one of the most significant architectural works of the late 20th century and is credited with demonstrating what became internationally known as the Bilbao Effect — the transformation of a declining post-industrial city through a single landmark cultural institution. Prior to the museum's opening, Bilbao was an economically depressed city recovering from the collapse of its iron, steel, and shipbuilding industries; within a decade the Guggenheim had become the anchor of a sustained urban and economic renewal of the entire riverside district. The building's exterior is clad in approximately 33,000 titanium shingles that shift in appearance with changing light conditions, appearing metallic and luminous in bright sun and matte and silver-grey under cloud. The assembled curved volumes — described by Gehry as a metallic flower — are organised around a central 50-metre atrium of glass and titanium. Limestone blocks and glass curtain walls complete the exterior material palette. Jeff Koons' monumental topiary sculpture Puppy (1992) — a West Highland terrier form covered in approximately 70,000 seasonal flowers — stands at the main entrance on the riverside promenade. Louise Bourgeois' bronze spider Maman stands at the building's northeast corner. The permanent collection focuses on large-scale contemporary works with particular emphasis on pieces that respond to the building's extraordinary gallery proportions. The largest gallery — Gallery 104, informally known as the boat for its curved floor plan, 130 metres in length — contains Richard Serra's The Matter of Time (1994-2005), eight weathered Cor-Ten steel ellipses and spirals, each weighing tens of tonnes, which have become the museum's defining installation. The museum collaborates with the Solomon R. Guggenheim Foundation on rotating loan exhibitions from the global collection, bringing works by Mark Rothko, Anselm Kiefer, and others to Bilbao on a regular basis.
