Koolhaas Library, Seattle
This striking glass and steel structure, completed in 2004, was designed by the award-winning Dutch architect Rem Koolhaas as a replacement for the city's 1960 Central Library.
The unusual shape of the building was once a source of controversy, but the Koolhaas Library is now regarded as one of Seattle's architectural highlights.
The 11-floor library includes works of art worth a staggering $1 million and an innovative "Books spiral", allowing visitors maximum access to the collection.
