Inside a $185 million Switzerland mansion that has walls covered in 24-karat gold

The seven-floor home, located at the St. Moritz ski resort in Switzerland, was "designed to make a billionaire's jaw drop," listing agent Senada Adzem of Douglas Elliman Real Estate told "Secret Lives of the Super Rich." At $185 million, it's the most expensive home on the market in Switzerland at the moment and is reportedly owned by an unnamed billionaire.

With perks like a private ski lift to the slopes, a $1.3 million home theater, an underground lake, and rooms that surround you with 24-karat gold walls, this home is truly a playground for the wealthy.
