The strikingly beautiful Romanesque style Preston Castle, on a hill in Ione, was actually the administration building for the Preston School of Industry, the first major attempt in California at rehabilitating, instead of just imprisoning, young offenders. Opened in 1894, the Preston School of Industry became a leader in the juvenile prison reform movement by giving convicted boys a real chance at life by educating them not only in academics, but in all of the useful trades of the time.

Closed in 1960, when the Preston Youth Authority moved into a new administration building down the hill, the Preston Castle was left to deteriorate due to weather, vandalism, and general neglect. It now serves as a vacant, but vitally important landmark for Ione, Amador County, and the Mother Lode. It is a California State Historic Landmark and is on the National Register of Historic Places.

Numerous Paranormal research groups have investigated this location and report that it is one of the most active sites they have had the pleasure to experience. Experiences at the castle have included EVP, humming, whispers, touching, channeling, and seeing and recording orbs and apparitions.

The Mission of the Preston Castle Foundation is to preserve, rehabilitate, and utilize the historic Preston Castle site. To help raise money for this important project, the Foundation sponsors several fund raising events throughout the year and special tours.
