Those hoping to take a haunting tour of the home of Chicago's most notorious serial murderer will be dismayed to hear that Holmes' hotel is no longer in operation. That's right—the Englewood Post Office is the only structure that still stands on the site where H.H. Holmes erected his contemporary dungeon. The town has been through many changes since then, but the location of Holmes' hotel remains the same today as when it first opened its doors. Holmes was born in 1874 in Ohio. He moved to Chicago when he was young and became one of the city's most prolific murderers. His "torture room" contained over 100 instruments used by him or his staff to subdue their victims before they were killed. Holmes is said to have killed at least five people in his hotel alone, but experts believe the true number may be higher than that. He is also known for killing people the world over; although most of his victims were American, he is also reported to have killed Europeans and South Americans. Holmes committed suicide in 1911 after being arrested for another murder. Before he did so, he left a note saying that he was doing this for money--but also because he was sick of living. Since his death, several books and films have been made about his life and crimes. In addition, there are now tours available of the hotel where he lived out his final years in prison.
