In recent days, it has been decided that you can enter the Pantheon after buying a ticket. According to the authorities of Rome, this is due to the urgent need to maintain the monument.
Tourists from Italy and abroad will have to buy tickets; Romans will have free entry to the monument. Free entry to the Pantheon will also be granted to persons under 18 years of age; people under 25 can buy a ticket for 2 euros.
