H.H. Holmes Murder Castle Site

The site where America's first documented serial killer, H.H. Holmes, operated his infamous "Murder Castle" during the 1893 World's Columbian Exposition. The three-story building featured secret passages, soundproof rooms, gas jets for asphyxiation, and a crematorium. Holmes confessed to 27 murders though the true number may be much higher.

The H.H. Holmes Murder Castle stood at 63rd Street in Chicago's Englewood neighborhood, built during 1889-1891 by Herman Webster Mudgett—better known as H.H. Holmes, America's first documented serial killer. Dubbed "The Beast of Chicago," "The Devil in the White City," and "The Torture Doctor," Holmes constructed his three-story building with secret passages, trapdoors, soundproof rooms, doors that locked from the outside, gas jets to asphyxiate victims, and a kiln to cremate bodies.

Holmes hired and fired multiple construction crews throughout construction so no single worker would understand the building's sinister layout. After completion in 1891, he placed newspaper ads offering jobs for young women and advertised the building as a lodging house. When the World's Columbian Exposition arrived in 1893, the building became known locally as the "World's Fair Hotel."

While sensational tabloid coverage estimated Holmes killed between 133 and 200 victims, historians suggest a more conservative figure of around nine confirmed murders—primarily people he already knew. The building never actually functioned as a hotel, with the first floor housing storefronts and the second floor containing long-term rental apartments. An unfinished third floor was advertised as hotel space but never opened to the public.

Holmes was eventually captured and convicted for the murder of his business partner Benjamin Pitezel and Pitezel's three young children—Howard, Nellie, and Alice—whom he killed in 1894. He received the death penalty and was hanged in Philadelphia on May 7, 1896, about a week before his 35th birthday.

In 1895, while Holmes sat in prison, the Murder Castle was gutted by a suspicious fire after witnesses reported seeing two men enter late at night. The structure remained standing until 1938 when it was demolished. A U.S. Post Office now occupies the site at 63rd and Wallace Streets.

Postal workers and visitors have reported ghostly sightings in the building's basement for decades, particularly in areas believed to correspond with Holmes's underground chambers. Cold spots, unexplained sounds, and unsettling presences have been documented, as if the souls of Holmes's victims still linger where they met their horrific ends.
