Preparedness Day bombing

The corner of Steuart and Market Streets marks the site of the Preparedness Day bombing, the deadliest act of terrorism in the history of San Francisco. On July twenty-second, nineteen sixteen, a massive parade intended to advocate for United States entry into World War I drew tens of thousands of spectators to this area. At two oh six in the afternoon, a suitcase packed with dynamite and steel shrapnel detonated near the intersection, killing ten people and wounding forty others.
