The Four-Day Itinerary Across Paris, Lourdes and Metz

Pope Léon XIV will make an apostolic journey to France from 25 to 28 September 2026, visiting Paris, Lourdes and Metz at the invitation of the president of the Republic, French church authorities and the director-general of UNESCO. French authorities are treating the visit as a major public order operation because of the exceptional crowds expected at several open-air events.

The Paris leg, on 25 and 26 September, includes a visit to UNESCO headquarters, solemn vespers at Notre-Dame de Paris, a prayer vigil with young people at the Stade de France, and an open-air mass on the Concorde–Champs-Élysées axis for which organisers expect about 600,000 people. On 26 and 27 September, the pope will appear in Lourdes, including at the grotto of Massabielle and at a Sunday mass in the sanctuary meadow, where 150,000 people are expected. The final day in Metz features a 2.2-kilometre papamobile route and a mass for peace at Saint-Étienne cathedral; 12,000 people are expected, including 2,000 inside the cathedral.

Preparations have been running for weeks among the Paris police prefecture, the Hautes-Pyrénées prefecture, the Moselle prefecture and national security forces, in coordination with Vatican security, Swiss guards and local elected officials. Security will operate under the reinforced Vigipirate posture in force since 22 June 2026, which focuses on countering drone threats, securing tourist sites and protecting public buildings.

Under the 2017 internal security and counter-terrorism law, protection perimeters will be established around the pope. Everyone with a reservation to enter the papal zones will be searched and patted down; refusal means no access. In Paris, 15,000 personnel will be on the ground on 25 and 26 September, including police, gendarmes, mobile force units and soldiers from Operation Sentinelle, with about 14,000 positioned to prepare the arrival. Specialist capabilities include bomb disposal units, marksmen, motorcycle escorts and the BRI, RAID and GIGN intervention units. Around 2,500 Paris firefighters will be deployed, supported by the Red Cross and the Order of Malta. In Lourdes, the security system will be active from 23 to 28 September, with more than 2,000 police reinforcements, additional military and Sentinelle units, more than 3,000 security personnel in total, and over 1,100 gendarmes.

Inside the Largest Public Order Operation of the Visit

Why the Paris Concorde Event Is the Hardest Test

The expected 600,000 people for the open-air mass on the Concorde–Champs-Élysées axis create a crowd-management problem unlike a stadium event. A long, open urban avenue has many possible access points, limited natural chokepoints and large frontages that have to be secured without completely paralysing central Paris. The published plan addresses this with reserved-entry perimeters, individual searches and a layered force of 15,000 officers and soldiers.

The Vigipirate Posture Puts Drone Threats at the Centre

The reinforced posture introduced in June 2026 explicitly targets drone threats, tourist sites and public buildings. A papal visit combines all three categories in one moving schedule, which explains why the operation includes marksmen, deminers and specialist intervention units as well as ordinary police and gendarmes. The practical consequence is likely to be strict airspace and perimeter controls around each event site.

Lourdes and Metz Are Smaller in Scale but Still Capacity-Constrained

In Lourdes, the sanctuary has already closed registration because it reached maximum capacity, with 50,000 people expected on Saturday evening and 150,000 on Sunday. Security gates and body checks at entrances, plus 3,000 security personnel, suggest access will be managed tightly. In Metz, the cathedral itself holds only 2,000 of the 12,000 expected, meaning most people will follow the event from outside the building along or near the 2.2-kilometre papamobile route.

What Pilgrims and Residents Should Expect

  • If you have a reservation for a papal event, arrive early and expect a mandatory search; refusal means you will not enter the protection perimeter.
  • In Paris on 25–26 September, follow the police prefecture's announcements for exact perimeters, site closures and traffic restrictions, which will be released as the event approaches.
  • Do not travel to Lourdes for the Saturday evening or Sunday events without confirmed access, because registration is closed and sanctuary capacity has been reached.
  • In Metz, plan for closures along the 2.2 km papamobile route and note that only 2,000 of the 12,000 expected at Saint-Étienne cathedral can be accommodated inside.
