I Need A Unique Wedding Location In CA

Hi,
I live in Los Angeles and I have been looking for a site to have my Halloween/Masquerade wedding. I would really like to find a building with a gothic feel, or even a castle look. Actually, anything that is old, maybe a little eerie, yet beautiful, would be perfect. If it has a ballroom, that would be a big added plus! I`m looking for something more than a hotel or hall with character--I`m hoping for a setting! Also, If is it a few hours drive from LA, that would be okay.

Thank you so much,
Robin
