Why should the castle be restored?

Being well over 125 years old, the Preston Castle overflows with craftsmanship both inside and out that is rarely, if ever, seen in modern buildings. Preservation of the castle means saving a historically significant California landmark. The speed at which the Preston Castle can be recovered also depends upon the support of its members and volunteers, and the longer the Castle goes without repair, the more history California loses forever.

A structural analysis of the castle is underway to determine the full extent of the repairs necessary to preserve and rehabilitate the Preston Castle. The full cost is unknown at this time, but ranges upward from $25-$30 million.

What are the future plans for use of the Preston Castle?

Because the building is so large, the castle will probably be a multi-purpose building. Possible uses might include an event center, culinary school and restaurant, boutique hotel, museum, retail shops and office space. The Foundation’s goal is for the building to be self-sustaining.
