City: Washington, D.C.
Considering the United States' status as the most dominant superpower the world has ever known, the White House is a worthy suspect for housing an Illuminati Headquarters. Its many secrets and labyrinth layout, in addition to the presence of underground bunkers and a situation room, would make it an ideal hideout for Illuminati thugs. Maybe that explains why the President became a spineless robot upon being sworn into office. "They" have the real power. Some say they can clearly see a satanic pentagram embedded in the White House's upper-facade. Others say the presidential quarters sit at the apex of a street network laid out in the shape of a pentagram. Judge for yourself. Or head over to Jesus-is-Savior for all the proof you could ever need.
