H.H. Holmes and His Murder Castle: The Hotel Designed for Killing During the 1893 World’s Fair
Imagine checking into a hotel and discovering that the walls have hidden passages, the rooms are sealed gas chambers, and the basement contains a dissection table and a crematory. For the victims of H.H. Holmes, this was not imagination — it was their final reality.

Dr. Henry Howard Holmes — born Herman Webster Mudgett — is widely considered America’s first documented serial killer. But that barely scratches the surface. Holmes did not just kill people. He built an entire three-story building specifically designed for murder — and he did it during the 1893 Chicago World’s Fair, an event that drew 27 million visitors to the city. Nobody knows exactly how many of them he killed.
Holmes arrived in Chicago’s Englewood suburb in 1886 and took over a pharmacy — after the original owner mysteriously disappeared. Using money from frauds and insurance scams, he purchased a large lot and began construction on what he called “The Castle.” The building was a physical manifestation of a psychopath’s mind: secret passages, soundproof chambers lined with asbestos, gas chambers controlled from his office, a basement crematory, and a dissection table where bodies were prepared for sale to medical schools. Holmes rotated through dozens of construction crews specifically so no single person could understand the building’s deadly layout.

When the 1893 World’s Columbian Exposition opened, Chicago flooded with tourists — young women from small towns, couples seeking adventure, people with no local connections. Holmes turned his building into a hotel and opened his doors. Many guests never checked out. Holmes was charming, handsome, and persuasive. He promised jobs, marriage, a new life. His known victims include Julia Smythe and her daughter Pearl, secretary Emmeline Cigrand, and sisters Minnie and Anna Williams.
He also killed Benjamin Pitezel, his insurance fraud accomplice, then murdered three of Pitezel’s five children — burning two of them in a stove in Canada. Holmes confessed to 27 murders, but investigators believe the real count could be as high as 200 — most of them transient World’s Fair visitors never reported missing.

Holmes was caught in 1894, pursued by the Pinkerton Detective Agency. When authorities entered The Castle, they found bones, bloodstains, vats of acid with human remains, and a crematory in heavy use. Holmes was convicted of Benjamin Pitezel’s murder and hanged on May 7, 1896. He requested burial in concrete — supposedly to prevent body theft, though some believe it was his final attempt at control. The Castle was gutted by a mysterious fire shortly after. Its secrets went up in flames.
