PARIS — French President Emmanuel Macron’s office is courting Saudi cash to turn what was once the country’s biggest theme park into a manga-themed attraction.

According to half a dozen diplomatic, government and industry officials — all of whom were granted anonymity to speak candidly about a project one person characterized as “highly confidential” — the Elysée Palace has for several months held discussions with potential Saudi Arabian investors about the revival of Mirapolis, which closed in 1991 due to financial issues and has remained abandoned since.

A subsidiary of the Saudi Public Investment Fund called the Qiddiya Investment Company is at the center of the negotiations. The Saudi sovereign wealth fund recently opened an office in Paris.
