Casa de las Brujas — the House of the Witches in Guanajuato

The Casa de las Brujas (House of the Witches) in Guanajuato was built in 1845 and was owned by a prominent local family before being associated with dark practices. According to local legend, the house was the site of witchcraft rituals during the 19th century, and the entities summoned during those rituals never departed. Staff and visitors report EVP recordings capturing whispered conversations in archaic Spanish, doors slamming throughout the house without wind, and a heavy, oppressive atmosphere that concentrates in the upper rooms. Some accounts describe seeing candles light themselves in empty rooms and the silhouette of a woman performing rituals visible in the windows at night. The house sits in the colonial heart of Guanajuato, a UNESCO World Heritage city built in a narrow valley and famous for its colourful houses stacked on steep hillsides, its underground streets (former river channels), and the Mummies of Guanajuato. The concentration of the supernatural in Guanajuato is remarkable even by Mexican standards — the city's geography, history, and cultural traditions seem to converge in ways that produce an unusually dense haunted landscape.
