The Washington Monument is a 555 foot obelisk located on the National Mall in Washington, D.C., honoring America's Founding Father, Revolutionary War hero and the first president of the United States of America George Washington.
During the fourth year of Superman's Regime, after the death of Huntress a few months earlier, her friend Renee Montoya went into an alcoholic fury for revenge against Superman. Montoya overdosed on super pills and challenged Superman to a fight in Washington, D.C.. In the climax of their fight, Montoya picked up the Washington Monument and hit Superman with the obelisk before succumbing to her overdose. She died at the base of the monument.
