The Oklahoma City bombing memorial is carefully and thoughtfully designed place. In addition to the Field of Empty Chairs, it includes the element called the Gates of Time, which are described this way:

Monumental twin bronze gates frame the moment of destruction – 9:02 – and mark the formal entrances to the memorial. On the eastern gate, 9:01 represents the last moments of peace, while its opposite on the western gate, 9:03, represents the first moments of recovery. Both time stamps are inscribed on the interior of the monument, facing each other and the reflecting pool. The outside of each gate bears this inscription: We come here to remember those who were kind, those who survived, and those changes forever. May all who leave here know the impact of violence. May this memorial offer comfort, strength, peace, hope, and serenity. –Wikipedia
