Mansion listed at €12,000,000

This mansion is a place that someone would live in at the top of the upper class, it's listed at €12,000,000, though most upper class people live in villas that are listed somewhere around €1,500,000

This mansion is 150,000m2, with 3400m of floor space, with an indoor and outdoor swimming pool, along with 8 bedrooms. 

I also found an €18,000,000 castle that was for sale.
