King Gillette Ranch
(Calabasas, CA)

Nestled in the Santa Monica Mountains, this Historic Spanish Colonial Revival mansion was built for razor magnate King C. Gillette in the 1920s. The mansion and surrounding structures were designed by Wallace Neff, known as the Architect of California’s Golden Age.  The ranch includes 588-acres of scenic parkland and original landscaping, including a formal courtyard and fountain, a man-made pond, and an alley of eucalyptus trees.

The King Gillette Ranch is currently owned and managed by the Mountains Recreation and Conservation Authority in cooperation with the Santa Monica Mountains National Recreation Area unit of the National Park Service, the Santa Monica Mountains Conservancy, and California State Parks.
