Was the Beverly Hillbillies Filmed in a real Mansion?

Question

I'm watching the Beverly Hillbillies and was wondering if anyone here knows if they filmed it in a real mansion?

If so I'd love to take a drive by it one day if it's still standing? Or if they filmed it in a studio, which studio was it filmed in?

Answer 1

The intro part showed a real mansion. But the interior shots were done in a studio.
