Perched high above the sparkling coastline of Villefranche-sur-Mer at nearly 600 meters (1,968 feet) above sea level, this luxury estate—aptly nicknamed "the roof of the world"—offers one of the most awe-inspiring panoramas in the south of France.

The beautifully preserved 19th century residence is located in the residential area of Lanterne in Nice, France, just a few steps from the area’s beaches, restaurants and shops.
