Guggenheim Museum Bilbao in Spain.

The Guggenheim Museum Bilbao, designed by the deconstructivist architecture master Frank Owen Gehry, born in Toronto, Canada, was officially completed and put into use in 1997. Its unique shape, peculiar structure, and innovative materials immediately attracted worldwide attention. In the galaxy of human architectural creations in the 1990s, the Guggenheim Museum Bilbao undoubtedly belongs to the greatest, like the Sydney Opera House, they both belong to the future architecture that has come ahead of time, and are urban poems not written in earthly language. The museum covers a total area of 24,000 square meters, with 11,000 square meters of exhibition space divided into nineteen exhibition halls, one of which is also one of the largest art galleries in the world, with an area of 130 meters by 30 meters. The entire museum structure was gradually designed by architects using a computer software for aerodynamics (introduced from the French military aircraft manufacturer Dassault and called CATIA). The museum uses glass, steel, and limestone in its building materials, with some surfaces covered in titanium, echoing the city's long-standing shipbuilding tradition.
