The mayor of Las Palmas de Gran Canaria, Carolina Darias, described the visit as "historic" and of "international dimension," emphasizing that the awarding of the Keys is a "gesture of respect, hospitality, and formal welcome to the city."

This honorary distinction recognizes the "historical and institutional significance" of the first visit by a Pontiff to the Canary Islands, as well as the city's "close relationship" with the Holy See over more than seven centuries.

The Keys of the City are one of the council's highest protocolary recognitions, originating from medieval walled cities as a symbol of trust.

In Las Palmas de Gran Canaria, this symbol holds a special connection to the city's fortified past, which included walls like the ancient Puerta de Triana.

Leo XIV will be the fifth personality to receive this distinction. The last presentation was in 1996 to several Nobel laureates and biochemist Santiago Grisolía, on the occasion of their investiture as Doctors Honoris Causa by the University of Las Palmas de Gran Canaria.

The Pontiff's visit is considered a historic event for the archipelago, not only for its religious significance but also for its institutional and diplomatic character as head of state of the Vatican City.
