The Science Fiction Museum and Hall of Fame is the world's first museum devoted to the ideas and experiences of science fiction.

Exhibitions focus on science fiction literature and media while encouraging visitors to envision new futures for humanity.

The museum's Hall of Fame pays homage to its practitioners — writers, artists, publishers and filmmakers.

The Experience Music Project explores creativity and innovation in popular music. Exhibitions include cutting-edge music technology, exploring the roots of rock 'n' roll in jazz, soul, gospel, country and the blues, as well as rock's influence on hip-hop, punk and recent genres.

Exhibits include rare artifacts and memorabilia, and visitors experience the creative process by listening to musicians tell their own stories.

Amateurs can test their talents in the Project's music lab.

Both museums are housed in a spectacular structure designed by architect Frank O. Gehry at the Seattle Center.
