A library that looks like a crystal diamond? The Seattle Central Library is one of the most architecturally daring public buildings in America — and it’s completely free to explore.
Designed by Rem Koolhaas, this 11-story glass-and-steel landmark in downtown Seattle features a continuous four-floor ‘book spiral,’ a stunning red 13th-and-14th-floor corridor, public meeting spaces and one of the best city views from its upper floors.
A must for architecture fans, book lovers and curious minds of all ages. Tip: take the free public tour (or grab the self-guided map at the welcome desk), ride the escalators through the glowing red floor, and finish on level 10 for a panoramic view of downtown.
