The National Book Festival attracts both writers and readers of some of the world's best-loved books. Several award-winning authors head to the National Mall for this event every September to be on hand for autograph signing and seminar appearances. The kids will love meeting some of the characters from some of their favorite books as they come to life here and are available for photos.

The National Building Museum presents several fascinating exhibits that cover architecture, construction and engineering. And while several of the country's most famous structures are spotlighted, the actual museum building itself is an exhibit in its own right. This amazing venue features massive columns, a picturesque fountain and a highly decorated ceiling that reaches 15 stories upward. Several interactive exhibits are part of the many highlights, including temporary exhibits that focus on the development of ghettos, roads, factories, parks and more. If it was built, the chances are its story is within the walls of this incredible museum.
