I saw this on another site and thought I would share it here:
Travel Advisory for Italy: 2025 Jubilee year
PSI: Based on communications with Italian officials and the Italian Embassy, as well as my personal experiences traveling to Italy, please note the following:
Due to the 2025 Jubilee and the significant increase in visitors to Rome and Italy, there will be heightened security measures from now through the end of 2025. This includes an increased presence of police, law enforcement, and military personnel.
As in previous Jubilees, enforcement of passport regulations will be stricter. Travelers are advised to carry their original passports at all times. Copies of passports, which may have been accepted or overlooked in the past, are now unlikely to suffice. Non-compliance could result in fines or other penalties.
For your safety and convenience, consider using anti-theft options to secure your passport while traveling. These enhanced measures are partly aimed at offsetting the increased costs of security during this busy period.
