This castle that was once owned by French royals can be yours for $17 million

A historic château in Aix en Provence is now up for sale - and if you have a spare $17 million, it can be yours.

The castle, which dates back nearly 1,000 years, was previously owned by the French royal family and is now on the market with Sotheby's International Realty, Bloomberg reported.

The current owners, Ghislaine Pillivuyt and her husband, Bertrand, inherited the property in 2006 and have been running it as a family business - opening the house and garden to the public, using it as a wedding venue, and running a bed and breakfast there.
