The Guggenheim Museum Bilbao is a contemporary art museum located in the city of Bilbao, in the Basque Country of Spain. It was designed by Canadian-American architect Frank Gehry and opened to the public in 1997. The museum is a significant architectural landmark and is often cited as one of the most important buildings of the 20th century.

The museum's collection focuses on modern and contemporary art from the 20th century, with an emphasis on the work of Basque and Spanish artists. The permanent collection includes works by major figures such as Pablo Picasso, Mark Rothko, Willem de Kooning, and Andy Warhol, among others. The museum also hosts a variety of temporary exhibitions throughout the year, featuring works by international artists.

In addition to its impressive collection, the museum's distinctive architecture has become a major attraction in its own right. The building's exterior is characterized by its curving, titanium-clad forms, which are intended to evoke the surrounding hills and river. The interior of the museum features large, open spaces that allow for flexible exhibition layouts, as well as a central atrium that is topped by a glass roof.
