Biblioteca Estatal Justo Sierra — the haunted prison-turned-library of La Paz

The Biblioteca Estatal Justo Sierra (State Library) in La Paz, Baja California Sur, occupies a building founded in 1918 that has served as a prison, a hospital, and now a public library. The building's multiple institutional uses — each associated with suffering and death — have given it a layered haunted reputation. Library staff describe hearing footsteps in the stacks after hours, books being found pulled from shelves and arranged in patterns on the floor, and EVP recordings capturing voices speaking in both Spanish and an indigenous language. Some staff members have reported seeing a figure in what appears to be prison clothing standing in the doorways of the former cells that now house book collections. La Paz, the capital of Baja California Sur, is a quiet city on the Sea of Cortez that belies the violence of its history — pirates, the Mexican-American War, and the harsh conditions of its territorial prisons have all left their mark. The library's transformation from a place of punishment to a place of learning has not erased the spiritual residue of its former occupants.
