Barbara Clearly Realty
The mansion, which had stood unused for six decades, was initially listed for $34 million in 2006, and later relisted for $25 million in 2008. It later reappeared on the market for $19.8 million last March, shortly after Clark died in a New York hospital.
Clark bought the house in 1951, but never furnished it and never moved in, though it's been impeccably maintained. The 12,766-square-foot, French-chateau-style mansion features nine bedrooms, six full bathrooms, and three half-baths. It sits on a 52-acre piece of land.
