The Guggenheim Museum Bilbao is a museum of modern and contemporary art, designed by Canadian-American architect Frank Gehry, and located in Bilbao, Basque Country, Spain. The museum was inaugurated on 18 October 1997 by King Juan Carlos I of Spain.
It is built alongside the Nervion River, which runs through the city of Bilbao to the Cantabrian Sea. The Guggenheim is one of several museums belonging to the Solomon R. Guggenheim Foundation. The museum features permanent and visiting exhibits of works by Spanish and international artists.
One of the most admired works of contemporary architecture, the building 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. 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.
