The pontiff began his stay in Catalonia with a message in Catalan from the Barcelona Cathedral, where he expressed his "great joy" to commence the visit. He later presided over a prayer vigil at the Olympic Stadium with 37,000 attendees.

Pope Leo XIV's itinerary in Barcelona features a significant event on Wednesday: the blessing of the tower of Jesus at the Sagrada Familia, to which he will travel by popemobile. This visit places the city in the international spotlight and presents organizational and security challenges.

The media outlet betevé has prepared a special broadcast schedule to cover every moment of the pontiff's stay, featuring 20 hours of live programming. Additionally, two giant screens have been set up at Plaça de les Glòries Catalanes and the Arc de Triomf for citizens to follow the events from the street.
