This $50 million mansion was once owned by American royalty—take a look inside

The former home of a Vanderbilt heiress — who was once one of the richest women in America — is on the market for $50 million.

The 20,000-square-foot, six-story townhouse on New York City's Fifth Avenue sits directly across the street from Central Park in one of the swankiest neighborhoods in the country.

What's it like to live in this mega-home? CNBC's "Secret Lives of the Super Rich" goes inside with exclusive access to the urban mansion on an upcoming episode. Here's a first look inside:

The palatial Gilded Age home once belonged to Emily Thorn Vanderbilt Sloane, granddaughter of shipping and railroad magnate Cornelius Vanderbilt, who built the family fortune.

The property, which Sloane purchased in 1925 for $450,000, was designed by the same firm that developed iconic Grand Central Station, and many of the architect's original features are still intact at the historic landmark.

"All of our prospective buyers are ultra high net worth individuals that will use [the townhouse] for their families as one of their homes," Douglas Elliman broker Tristan Harper tells "Secret Lives of the Super Rich."
