Remnants of a long lost golden era, this amazing mansion looks like something out of The Great Gatsby. However it’s a remnant of the Golden Automotive Era, when Detroit was once an elite American city.

Edgemont is a Jeffersonian jewel surrounded by 572 acres in the foothills of the Blue Ridge Mountains.

The Beaux Arts-style residence was inspired by Versailles, built by the architects behind Grand Central Station, Warren & Wetmore, for a New York stockbroker-turned governor of Rhode Island in 1905. In 1925, it was purchased by Emily Thorn Vanderbilt Sloane White, granddaughter of railroad tycoon Cornelius Vanderbilt.
