As you continue your stroll along Pennsylvania Avenue, you reach the Department of Justice on the left and the J. Edgar Hoover Federal Bureau of Investigation Building on the right. You stop to look at the large panels on the Pennsylvania Avenue side of the Hoover Building. They tell the story of some of our Presidents: George Washington, John Adams, Thomas Jefferson, James Madison, James Monroe, Abraham Lincoln, Theodore Roosevelt, and Woodrow Wilson. Above the panels fly replicas of the American flag as it looked at different times in our history.
