We come here to remember those who were killed, those who survived and those changed forever. May all who leave here know the impact of violence. May this memorial offer comfort, strength, peace, hope and serenity.

Through the Oklahoma City National Memorial & Museum, the world will never forget the 168 who died in the April 19, 1995, bombing of the Alfred P. Murrah Federal Building.

The Memorial is comprised of two separate components, each pays tribute to the victims of the tragedy in a distinctive way. The 3.3-acre Outdoor Symbolic Memorial includes the Gates of Time, which mark the time before and after the bombing took place, and the Field of Empty Chairs, which memorializes each of those killed. The Survivor Tree, a symbol of Oklahoma's resilience, is an American elm that withstood the full force of the bomb's blast.

Inside the 50,000-square-foot Memorial Museum, interactive exhibits offer a contrast between the immense brutality of the senseless act and the tenderness of the city's response. This chronological, self-guided experience takes you through the story of April 19, 1995, and the days, weeks and years that followed. For a taste of the museum before you arrive, download the mobile app from the Apple App Store or Google Play.

Experience the lessons learned from the bombing, leaving you knowing the world holds far more good than bad. Walk through the events of that morning — hear from the investigators, rescuers, survivors and family members of those who were killed. See how the Oklahoma City community and people across the nation came together to support each other in a time of great need.

Museum admission is $15 for adults, $13 for seniors 62+, $13 for military with ID, $12 for students 6-17 or college student with current ID, and free for children five years and younger. Winter Hours have now begun at the Memorial Museum and will continue through March. The Museum will now close at 6:00 p.m. daily, with the last ticket sold at 5:00 p.m. each day.

A Remembrance Ceremony is held annually on April 19 at the Outdoor Symbolic Memorial. It commemorates those who were killed, those who survived and those changed forever. Also each year, tens of thousands of runners from around the world lace up to participate in the Memorial Marathon. This is truly a Run to Remember, bringing the community together to celebrate life and hope.
