A Qatar prince has bought the Hotel Lambert mansion from the Rothschild banking family in a deal valued at around 80 million euros ($111 million), the estate agency handling the sale said.

"I can confirm that it has been sold," an official at Emile Garcin was quoted as saying in a Gulf Daily News report.

Hotel Lambert lies on the Ile St Louis, an exclusive island in the middle of the River Seine, a bridge away from the Notre Dame cathedral.

The mansion was built in 1639 for Jean-Baptiste Lambert, who was an adviser to the French monarch.

During the 19th century, it passed into the hands of Polish prince Adam Czartoryski who entertained the likes of composer Frederic Chopin, writer George Sand and painter Eugene Delacroix.
