Le Palais Royal in Hillsboro Beach, Florida is officially the "most expensive palace in the U.S." currently on the market, with a price tag of $139 million. The French-inspired Beaux Arts mansion found on Millionaires Mile is up for grabs through William P.D. Pierce of Coldwell Banker Residential Real Estate, offering over 60,000 square feet of living space on more than four acres. The home overlooks 465 feet of beachfront and comes with its own 192-foot private dock that is large enough to fit a 185-foot mega yacht and a 30-car underground garage. Though the palace isn't move-in ready just yet—construction is set to be completely done by the end of 2015—the $139 million includes the finishing and these concept photos will give you an idea as to what the finished product will look like.
