French President Emmanuel Macron is floating plans to woo President Donald Trump with a rare dinner at one of history’s most ornate palaces.

Macron is already set to indulge the U.S. president at the Alpine spa resort of Evian-les-Bains from June 15 to 17, but two French officials familiar with the matter told Politico that he could take things one step further by appealing to Trump’s well-known royal tastes. The Palace of Versailles, which became the envy of Europe after its construction by King Louis XIV in the late 17th century, rarely serves as a location for a diplomatic reception. Paris may be betting that an exception is well in order to flatter Trump at a time of strained U.S.-European relations.
