Huguette Clark's House (Former)

Huguette Clark is the socialite daughter of
William Clark, a U.S. senator and Montana tycoon who made a killing from copper mines, railroads and Las Vegas property.

Her birth raised eyebrows in high society because her father - the second-richest man in the U.S. at one point - was 39 years older than her mother and no marriage license was recorded.

In 1952, Huguette Clark purchased this property, and as of 2010, has never moved in.

Sold to fashion designer Reed Krakoff for $14.3 million in 2014.
