Est. 1894 · California Juvenile Justice History · Romanesque Revival Architecture — Mother Lode · Unsolved 1950 Murder
California legislators in the late nineteenth century decided that juvenile offenders should be reformed rather than simply imprisoned alongside adults, and they created the Preston School of Industry to act on that conviction. The cornerstone went down in December 1890 on a site in Ione, in the Sierra Nevada foothills of Amador County. Construction proceeded under a design that has since been recognized as the most significant example of Romanesque Revival architecture in the California Mother Lode. The school opened in June 1894.
The building — known colloquially as Preston Castle due to its imposing medieval silhouette — was constructed with rough-cut stone and features the round arches, thick walls, and heavy massing that characterize Richardsonian Romanesque. It commands a hillside above Ione, visible from considerable distance in every direction.
The school's rehabilitation philosophy was aspirational; the actual conditions were considerably harsher. Corporal punishment was documented as a standard disciplinary practice during the institution's operation. Boys were assigned work, subjected to strict schedules, and in the school's earlier decades faced physical consequences for rules violations.
The school produced an unusual cross-section of alumni. Country musician Merle Haggard — who carries a 'PSoI' tattoo — was a student, as were actor Rory Calhoun, actor Lee J. Cobb, and crime author Eddie Bunker. The school operated under this name until 1960, when new facilities were completed on the same property. The original castle building was subsequently vacated.
In 1950, an event occurred in the castle that was never resolved: head housekeeper Anna Corbin was found beaten to death inside a locked room. No conviction followed. The Preston Castle Foundation, which now holds the property, has preserved the building and opened it for tours and investigation events. Historical journalist J'aime Rubio conducted an extensive investigation into Corbin's life and death, published as Behind the Walls.

Anna Corbin was the head housekeeper at Preston Castle in 1950 when she was beaten to death inside a locked room. No one was convicted of the murder. The case remained open and unresolved, and her presence in the building became the central figure of the castle's paranormal reputation — documented by historical journalist J'aime Rubio in the book Behind the Walls, which treated Corbin's life and death with the rigor of a cold-case investigation rather than paranormal entertainment.
Ghost Hunters and Ghost Adventures both conducted investigations at Preston Castle, and both productions documented evidence they attributed to paranormal activity. The castle's formal paranormal programming, offered through the Preston Castle Foundation, explicitly includes access to the building's documented investigation hotspots.
The spirits of the boys who were incarcerated at the school across its 66-year operating history form a secondary layer of the reported phenomena. Investigation accounts describe disembodied voices in the dormitory areas, the sound of footsteps on floors where no investigators are present, and cold spots that localize in specific rooms rather than distributing evenly through the building.
The basement generates consistent documentation — investigators report EVP recordings, unexplained sounds, and equipment anomalies in the lower level that they do not attribute to structural causes. The building's Romanesque stone construction means ambient sounds carry and reflect in ways that can be difficult to source, which both investigators and skeptics have noted in accounts of events at the site.
The paranormal investigation season runs April through August, aligned with the foundation's regular tour calendar.
