4. Villa La Leopolda – $750 Million
You know what hasn’t appeared on this list yet? France—the entire nation seems to have a dearth of super-expensive living spaces. Fear not, though—the French Rivera delivers in a big way with the Villa La Leopolda. Located in the lovely town of Villefranche-sur-Mer. Built on an estate formerly belonging to King Leopold of Belgium—hence the name—Villa La Leopolda is $750 million worth of Mediterranean style luxury, with tiled roofs, lookout towers, and an extensive and impressive set of grounds.
The outdoor spaces are worth special mention. The botanical gardens attached to the estate are some of the most extensive in private hands, requiring over 50 gardeners with various specialties in order to maintain them. The collection includes both rare exotic plants and some of the most beautiful species from the region, making for a heady balance for those botanically inclined.
