Oklahoma City National Memorial and Museum

April 19, 1995 was one of those days in America's history when time stopped. A bomb decimated the Alfred P. Murrah Federal Building at 9:02 a.m., killing 168 people including 19 children in its blast. This museum and memorial was raised in honor of the people affected during the barbaric bombing. The museum gives visitors a chronological tour of the experience, starting with a history of terrorism in the United States. It later leads through an auditory "explosion" and the confusion caused from it, while the last exhibit is about hope, to display the community's resilience. Outside, the memorial is a place where visitors can reflect.

A TripAdvisor user recommends visiting at night: "The lighting really makes it a unique place to visit." Many like this Yelp.com user were very moved by the museum exhibits: "When I came to the photo of a baby and his personal memento -- a pacifier, I cried. And I'm crying even thinking about it today. We must never forget."

You'll find the Oklahoma City National Memorial and Museum right downtown on North Harvey Avenue. Admission to the memorial is free, but the museum will cost adults $10. Hours are Monday through Saturday from 9 a.m. to 6 p.m. and on Sunday from noon to 6 p.m. For more information, you can visit the National Park Service's website or the memorial and museum's website.
