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.®

The Oklahoma City National Memorial & Museum was created
to honor those who were killed, those who survived and
those changed forever by the 1995 bombing of the
Alfred P. Murrah Federal Building in Oklahoma City.
The Memorial and Museum are dedicated to educating visitors
about the impact of violence, informing about events
surrounding the bombing, and inspiring hope and healing
through lessons learned by those affected.
