Vatican ◊
Easter Sunday Mass & Christmas Eve Mass are traditionally celebrated at St Peter's Basilica.
Capacity is limited and it can be very hard sometimes to get tickets for these events so you must book far in advance, no less than 2 months usually.
Reservation Procedure:
The best way to get your ticket for Easter/Christmas Masses is to send your request directly to the Vatican between 6 to 2 months in advance.
If the number of your request is not very large, lets say a family numbering 2-6 tickets you will have a bigger chance of getting your tickets.
Normally the Vatican will reply to your home address with a letter notifying you that they have received your request and where to take the letter at the Vatican to collect tickets.
They will not confirm tickets have been issued until you go to the prefecture office for collection.
There you will either receive your tickets or a letter to say there was not enough availability.
Again, the sooner you make you reservation the more chance there is of availability.
The smaller the number of tickets requested the higher the chance of having your request granted so we suggest don't book extra tickets unnecessarily.
If you order a large number of tickets such a group or more than 10 tickets we recommend you to send the request together with a letter of your parish or some authority of the church.
Tickets are collected at the Preffetura Vaticana located just after the "Bronze Doors" at St Peter's Basilica normally from 5-4 days days before the event from 8am till 6 or 7pm depending if it's winter or summer
