Guggenheim Museum, Bilbao, Spain

Designed by Frank Ghery

One of the most admired works of contemporary architecture, the Guggenheim has been hailed as a "single 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.
