Pope Leo XIV will travel to Argentina in November 2026, and Argentine authorities are already assembling one of the largest security and transport operations the country has staged in recent years. The Buenos Aires provincial government will deploy 11,365 police officers at full capacity for the papal visit, with the heaviest concentration around the Mass in Luján, according to TN.
The operation ramps up gradually. It begins on Wednesday, November 4, with 626 agents and grows day by day until it peaks on Wednesday, November 11, when all 11,365 officers are on duty. The force draws on multiple branches of the Buenos Aires provincial police and covers prevention, public order, road safety, investigation and intelligence, plus specialized units, emergency teams and logistics.
Why it matters
The visit puts Pope Leo XIV, an Argentine, at the center of the country's public life for several days, and the scale of the preparations reflects both the expected crowds and the political sensitivity of the moment. President Javier Milei has publicly welcomed the trip, saying it "will serve to consolidate Judeo-Christian values," as TN reported. At the same time, the government has denied any friction with the Church and insisted the Pope will not deliver political messages during his stay.
The visit also lands in the middle of Argentina's electoral maneuvering. Milei is expected to attend the November 9 Mass at the Monument to the Spanish in Palermo alongside his entire Cabinet, and Mauricio Macri has been invited to the same ceremony. The possible overlap between the two leaders comes as La Libertad Avanza and the PRO negotiate the shape of the 2027 electoral map, according to TN.
Security detail by the numbers
The largest share of the deployment, 4,242 officers, will handle security and prevention, drawn from units including UTOI, FBA, GPM, the Rural Police and the AMBA and Interior security superintendencies. Another 2,230 cadets and police institute members will take part, along with 1,706 officers assigned to public order — among them 848 in the Infantry division and 848 in the Cavalry division.
Investigation and intelligence work will involve 1,164 officers from the areas of Investigations, Narcotics, Intelligence and Organized Crime. Road safety accounts for 878 agents. Specialized groups total 371: 265 from the Departmental Support Group (GAD), 34 from Jaguar, 26 from Halcón, 22 from Explosives, 20 from FOE and four negotiators. Emergency services add 260 people, including 200 firefighters, and 514 more are assigned to support and logistics such as communications, transport, social services, gender policies and prisoner transfers.
The government has stressed that planning is being coordinated with the Vatican, the City of Buenos Aires and the provincial government. Presidential spokesman Adrián Ravier said the Vatican teams will work jointly with national and jurisdictional agencies involved in the visit, and noted that members of the Holy See's advance delegation began arriving in the country on Monday.
Transport, road closures and the Luján Mass
The national government has announced a special transport operation running mainly from Sunday, November 8, to Wednesday, November 11, with some changes starting earlier and lasting through Thursday, November 12. It includes extra buses and trains, overnight rail service, temporary station closures and restrictions at airports, according to TN.
Road access to Luján will be significantly affected. Clarín reported that the Autopista del Oeste will be closed for 15 hours because of the Mass, and Infobae published guidance on routes, schedules, road closures, access points and what pilgrims can bring to the ceremony. Página|12 reported that, amid the economic crisis, residents are offering their homes so visitors can watch the Pope.
The government has also confirmed who will attend the encounter with Pope Leo XIV at the Palacio Libertad. Vice President Victoria Villarruel and the country's governors have been invited, but former presidents will not be present, according to TN. Chief of Staff Diego Santilli will represent the national government at the Luján ceremony, where Buenos Aires Governor Axel Kicillof is also expected.
Milei's attendance at the Palermo Mass is set for 11:30 on Monday, November 9, and officials confirmed to TN that all his ministers will join him. Sources close to Buenos Aires city government head Jorge Macri confirmed that Mauricio Macri received an invitation; people around the former president have not denied he will go, though no public confirmation has been issued.
What to watch: the final confirmation of Macri's attendance and how the security and transport plans hold up as crowds build toward the November 11 peak.
