Behind gates and perched on a private knoll with 360 views of the San Gabriel Valley sits the majestic 'Pyrenees Castle,' built in 1925 by Sylvester Dupuy as a replica of a chateau he admired in France during his childhood. The largest privately-owned property in the area, the Castle sits on just over 2.5 acres, walled and gated, comprised of multiple gardens and mature trees. The impressive driveway leads to a motor court with fountain ushering you to the main residence. A grand foyer serves as the center point for the two wings of the Castle, each a mirror image of the other. Multiple original architectural details abound, including four turrets, a stately wood-paneled living room and dining room with beamed ceilings, crystal chandeliers, original inlaid hardwood flooring and hand-painted stenciling. With multiple entertaining spaces in addition to the 10 bedrooms/11 bathrooms, opportunities abound for ways to configure the home for today's modern living. The separate 4 garages have living area above them with 2 bedrooms/2 bathrooms, bringing the total count to 12 bedrooms/13 bathrooms. With upgrades to the infrastructure, roof, bathrooms, plumbing, kitchen and so much more, this home presents a true opportunity to own a one-of-a-kind, trophy estate.
