World's Most Expensive Penthouse Drips in Bling, Has Panic Room

Speaking of panic rooms, the world's most expensive penthouse has one. $308M was the price tag of La Belle Epoque, a palatial three-bedroom duplex in Monaco with 17,500 square feet. Interior details include an enormous library, a dining room with platinum-leaf ceilings, movie screens that appear and hide with the touch of a button, walk-in wardrobes, a billiards room, a jacuzzi, spa and media room. Monaco is pretty much blue skies and sunshine 300 days a year, but if you're worried—about turbulent weather or, say, about break-ins—that panic room's got reinforced glass and surveillance cameras.
