The Chicago Murder Castle

The Chicago Murder Castle was first built in late 1887 finishing in 1888 and getting an upgraded 3rd floor in 1889. The Castle was built by Americas first documented Serial killer H.H.Holmes. It served as his main palace of death. He killed roughly 200, but only 27 fully documented.


The Castle features soundproof rooms, secret passages and a disorienting maze of hallways and staircases. The rooms were also outfitted with trapdoors over chutes that dropped Holmes’ unsuspecting victims to the building’s basement.

The basement was a macabre facility of acid vats, pits of quicklime (often used on decaying corpses) and a crematorium, which the killer used to finish off his victims.
