The History of Preston Castle

The history of Preston Castle begins with a change in how California treated young offenders. Reformers wanted a model built around education and trades rather than adult prisons. The building rose between 1890 and 1894 as the administration building of the Preston School of Industry, which opened in 1894 as one of the state's first attempts at rehabilitation.

The castle served the school until 1960, when operations moved to a new building nearby, and the original was left empty. Years of neglect followed. It joined the National Register of Historic Places in 1980 and is a California Historical Landmark. In 2001, the Preston Castle Foundation formed to restore the site and reopen it to visitors.

Architecture and Design

Preston Castle is one of California's clearest examples of Romanesque Revival architecture, with rounded arches, heavy masonry, turrets, and a weathered brick facade that sets it apart from other Gold Country buildings of its era. Inside, visitors find grand staircases, a chapel, a dining hall, and the former living quarters of students and staff.

The interior shows its age after long neglect, and part of the visit is seeing a building mid-restoration rather than polished. For many guests, that unfinished quality is what makes the place feel honest and alive.

Preston Castle Tours: What to Expect

Public Preston Castle tours run seasonally, generally on frequent Saturdays from April through August, in both guided and self-guided formats. Guided visits are led by trained docents through the first floor, second floor, and basement, with stories about the Preston School of Industry along the way. Self-guided tours let you move at your own pace on a one-way route.

For guided tours, plan to arrive about 15 minutes prior for a start at 9:30 AM, and allow approximately 90 minutes, which includes a museum, a short safety and history video, and the castle itself. Tours often sell out, so booking ahead is wise. The season also brings a range of formats:

  • Guided tours led by docents through the first floor, second floor, and basement
  • Self-guided tours along a one-way route at your own pace
  • Flashlight Tours after dark, with docents sharing history and stories
  • Sunset Tours on select evenings from April through August; in 2026 these fell on June 19, July 10, and August 21
  • Paranormal Investigation Tours for those drawn to the castle's ghost stories
  • Private group tours by arrangement

Cultural Significance

Beyond its ghost stories, Preston Castle holds real weight in Amador County's heritage. As the surviving centerpiece of the Preston School of Industry, it stands for an early chapter in how California approached juvenile reform, and the Preston Castle Foundation has made preserving that record its mission through restoration and public tours.

The site also serves an educational role, with docent-led visits that teach local and state history, and it has become a draw for heritage tourism that supports Ione and the wider county. Volunteers and members keep the building open and its story in front of new visitors each season.

A Reputation for the Paranormal

Preston Castle is one of California's better-known haunted buildings, and its paranormal reputation is a real part of why people visit. It has appeared on television programs including ‘Ghost Adventures’ (2008) and ‘Ghost Hunters’ (2004). Much of the lore centers on Anna Corbin, a castle housekeeper who was killed at the castle in 1950.

The foundation leans into that interest with dedicated paranormal investigation nights and a popular Halloween haunt each October, while keeping its daytime tours focused on documented history.

Best Time to Visit Preston Castle

The best time to visit Preston Castle depends on the experience you are looking for. Regular guided tours are seasonal, while special events keep the landmark active later in the year.

  • April to August: Regular public tours operate during this period, making late spring and summer the main visiting season
  • Spring and Fall: Mild temperatures and softer natural light make these seasons ideal for photography and exploring the castle grounds
  • Summer: Expect warmer weather, especially on the exposed hilltop
  • Weekdays: When available, weekday tours are typically quieter than weekends

If you are visiting after August, regular public tours have usually concluded, but the castle's calendar shifts to seasonal events. October brings its popular haunted experiences, while December features holiday-themed programs that showcase the historic property in a different light. As tour dates and special events can vary from year to year, it is always a good idea to check the foundation's latest schedule before planning your visit.
