Looking for a Southern estate? This 17,000-square-foot mansion, set on more than 18 manicured acres in Atlanta, might be just what you want to call "home sweet home."

The estate, listed at $48 million, is being offered fully furnished, and a walk inside reveals a collector's dream. The museum-like setting is decorated with artwork by Pablo Picasso, Henri de Toulouse-Lautrec and others. The venetian plaster ceilings are modeled after the Braccio Nuovo at the Vatican Museum. There are also 19th century French neoclassical bronze doors and Baccarat crystal from floor to ceiling.

Inside the 2,400-square-foot master suite, a Baccarat crystal and gilt bronze Louis XV chandelier, circa 1900, is on display. Step into the master bathroom, and you will see an onyx bathtub. The details don't end there. Surrounding the shower and water closet are custom art nouveau-inspired carved and deeply etched art glass panels as well as two-sided, custom 18-karat gold door pulls.

And for the wine connoisseur, a pair of antique Parisian bronze mausoleum doors lead to mahogany wine racks that hold more than 1,000 bottles.

The 2,500-square-foot limestone terrace, imported from Jerusalem (with actual fossils inside), offers expansive views of the sprawling estate. Also on the grounds, is a one bedroom, one bathroom pool house with a full kitchen and wet bar, which makes relaxing by the saline swimming pool easier.
