ALBANY — A 4,620-acre plantation in southwest Georgia is being put up for sale for the first time in 50 years, authorities said.

The Magnolia Plantation is being offered for sale by Florida firm Jon Kohler and Associates, which has been named as broker, The Albany Herald reported.

The land was purchased in the late 1950s by Charles Allen Thomas of St. Louis from the Nimmick/Minnix family and now is owned by the Thomas family, according to Jon Kohler and Associates. Charles Thomas was a scientist and an important figure in the Manhattan Project, the development of the first atomic bomb, the Florida firm said.

“At one time (Magnolia), totaled over 15,000 acres and was one of the most cherished private estates in the country,” Kohler and Associates said in a description of the property.

Officials say they hope to close on a sale of the property before Dec. 31.

The plantation is about 15 miles from Albany.
