A 12th-century castle that once belonged to a Rothschild is being auctioned for a staggering €425 million, or around $454 million.
Once sold, the castle and its grounds could be transformed into a new city development just outside Paris, a spokesperson for Ignace Meuwissen, a luxury real-estate agent who is handling the sale with his company Whisper Auctions, told Business Insider.
The 17-bedroom castle, known as Château d'Armainvilliers, dates back to the 12th century and is around 30 miles outside Paris, according to Mansion Global. It was once owned by Edmond de Rothschild, who sold it to King Hassan II of Morocco, a spokesperson for Meuwissen told Business Insider.
Meuwissen told Mansion Global that it's one of the most expensive real-estate listings in the world.
But despite its connection to royalty, a spokesperson said the castle "may not hold much historical value" to the future buyer and will likely be favored because of its large size. The castle is 2,500 square meters and has an additional 1,000 hectares of surrounding land.
