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.

Built in 1891, Villa l'Aiglon offer spectacular views over the French Riviera, set at the gates to Monaco in Roquebrune Cap Martin.
