The shy 69-year-old Augustinian missionary has eschewed the headline-grabbing protagonism of past pontiffs in favor of a quieter, less showy and more reserved way of being pope.

For 400 years, most popes escaped the Roman summer in the hilltop town of Castel Gandolfo, Italy. Then Francis stopped going, leaving the town a bit bereft.

Pope Leo will revive a centuries-old tradition on Sunday by taking a holiday at Castel Gandolfo, where residents of the lakeside town hope for a tourism boost after the late Pope Francis shunned taking a summer break.
