On the Market: John Kluge's Landmark Palm Beach Estate

A gaggle of Florida properties once owned by media mogul John Kluge -- considered the country's richest man by Forbes in 1987 -- has come on the market for $59 million. The five oceanfront homes collectively known as Casa Sin Nombre are located in the heart of Palm Beach. They were gifted by Kluge to his alma mater, Columbia University.

Kluge, who died in 2010 at age 95, attended Columbia on a scholarship and gave generously to the school in gratitude for the assistance he had been rendered.

Kluge used the four-acre compound to host charitable events and it is considered one of Palm Beach's landmark estates. The homes provide more than 21,000 square feet of living space and include the renovated and enlarged 12,000-square-foot garden house that Kluge lived in. It was built in 1935. Also included are a 6,000-square-foot oceanfront Mediterranean (pictured above) built in 1921 and three other structures for staff or guests.
