Casa de los Lamentos — the House of Laments in Guanajuato where a serial killer's victims cry

The Casa de los Lamentos (House of Laments) in the colonial city of Guanajuato was the home of a 19th-century serial killer who murdered multiple victims within its walls. According to local accounts, the owner of the mansion tortured and killed his victims in the basement, and their bodies were discovered only after his death or arrest. The house earned its name from the screams and laments that neighbours reported hearing from inside the building — sounds that continued long after the killer was gone. Today, the house is one of Guanajuato's most visited haunted locations. Visitors and investigators have captured EVP recordings of voices pleading for help, and those who enter the basement describe an overwhelming sensation of dread, the smell of decay, and the feeling of invisible hands grasping at them. The house sits in the heart of Guanajuato's UNESCO World Heritage historic centre, surrounded by the colourful colonial architecture and winding callejones (alleyways) that make the city one of Mexico's most beautiful. The contrast between Guanajuato's vibrant exterior and the horror within the Casa de los Lamentos reflects a broader truth about Mexican haunted locations — behind the beauty of colonial architecture often lies a history of violence.
