Location: Palm Beach, Fla.
The Skinny: Towering five stories above its neighbors, the turreted, Moorish-influenced El Castillo cuts a remarkable figure on the skyline of Palm Beach, Florida, and its height pays off in views that stretch from the Intracoastal Waterway to the Atlantic Ocean. The estate was originally constructed in 1920, with the keep added in 1929 from a design by Addison Mizner, the architect whose Mediterranean Revival style has become synonymous with South Florida. Mizner also designed and crafted (through his Mizner Industries) the terracotta Cuban tile, painted cypress ceilings, and iron lighting fixtures and railings that are preserved within the home. The attention to historic detail is impressive: an award-winning restoration in 2009 saw the home's Otis Elevator renovated, the flooring refurbished, and all hardware restored or faithfully replicated. Modern touches were also added, including a new wing with kitchen and family room, and walk-in closets in the bedrooms. The outdoor areas of the estate feature a Volk-designed pool house and a patio with wet bar high atop the tower. As eye-popping as the home is, the price is just as impressive: the historic estate is asking $26.4M.
