A compound of exceptional Palm Beach properties formerly owned by John Kluge, once ranked by Forbes as the world's richest man, has been listed for sale at $59 million. Kluge acquired the group of five residences on lushly landscaped grounds in the heart of Palm Beach's estate section over the course of 30 years before gifting them to his alma mater, Columbia University.

Kluge combined the five properties in 1995 to create a magnificent trophy estate which he named Casa Sin Nombre. It is comprised of exotically landscaped grounds with more than 21,000 square feet of living areas including the renovated and expanded 12,000-square-foot garden house built in 1935 which Kluge used as his main residence; a 6,000-square-foot ocean-front house designed in 1921 by society architect Addison Mizner in the Mediterranean Revival style; and three separate buildings to accommodate staff and/or guests.

The property, used frequently over the years by Mr. Kluge for charity events, is considered to be one of Palm Beach's most iconic estates. The ultra-private, over four acre compound is replete with exceptional ocean views and is ideally situated within easy distance of Worth Avenue stretching between Ocean Boulevard and South County Road.

Kluge donated the estate to Columbia as part of a $400 million pledge in 2007, earmarked exclusively for student scholarships. The Corcoran Group agents, Paulette Koch and Dana Koch, and Brown Harris Stevens agents, Carole Digges and Carole Hogan are representing the property on behalf of Columbia University. Christie's International Real Estate will provide global marketing services.
