Library Day at the National Building Museum

Discover Summer at the National Building Museum

Sign up to Discover Summer and make memories at the National Building Museum this summer. Can you think of one place every American town has—or should have? If you guessed playground, you're right!

Use your library card to gain free access to the National Building Museum’s indoor Playground. Playgrounds are part of our universal memory—a shared space of delight and discovery that transcends age, location, and time. By bringing typically public infrastructure indoors, THE PLAYGROUND creates an awe‑inspiring, nontraditional environment centered on the mental and physical benefits of play.

Designed for all ages, the installation encourages motion, exploration, and togetherness in an immersive environment where play becomes a shared social and cultural experience.

Registration is mandatory.
