While it’s not technically a castle, it has the size and structure of one, but in the form of probably the most unique penthouse outside of New York City or Los Angeles.

And it’s listed for $49.5 million in Boston, Massachusetts.

The wow-factor is off the charts just combing through the photos. It has dramatic views and marble flooring (probably don’t want to take a tumble down those stairs anytime soon), classic ivory overtones, a dining room that makes you feel you’re inside of a kaleidoscope, and, yes, a massive bar to watch Red Sox games even though you’re still crying over losing Rafael Devers to the San Francisco Giants.

The place is so elegant that it was featured on the popular Facebook page, Zillow Gone Wild, a real estate page that highlights interesting listings around the market. People were flabbergasted.

“I’ll go in 50/50 on the HOA with someone,” someone joked.

“Is that Tony Starks house?” one person asked.
