Guggenheim Museum Bilbao

The Guggenheim Museum Bilbao is a museum of modern and contemporary art in Bilbao, Biscay, Spain. It is one of several museums affiliated to the Solomon R. Guggenheim Foundation and features permanent and visiting exhibits of works by Spanish and international artists. It was inaugurated on 18 October 1997 by King Juan Carlos I of Spain, with an exhibition of 250 contemporary works of art. It is one of the largest museums in Spain.

The building, designed by Canadian-American architect Frank Gehry, was built alongside the Nervion River, which runs through the city to the Cantabrian Sea. A work of contemporary architecture, it has been hailed as a "signal moment in the architectural culture", because it represents "one of those rare moments when critics, academics, and the general public were all completely united about something", according to architectural critic Paul Goldberger. The museum was the building most frequently named as one of the most important works completed since 1980 in the 2010 World Architecture Survey among architecture experts. It changed the city quarter.
