Vatican Christmas Eve Mass in Saint Peter's Basilica
The Vatican's Christmas Eve Mass, often called Midnight Mass though celebrated around 10 p.m. on December 24, is the pope's principal Christmas liturgy inside St Peter's Basilica. Thousands attend in person with free tickets, while thousands more watch on screens in the piazza outside, and the Mass is broadcast worldwide.
Just before ten o'clock on December 24, the doors of St Peter's Basilica close on a nave already filled with roughly six thousand people, while several thousand more wait outside in St Peter's Square, watching the same Mass unfold on giant screens under whatever December weather Rome offers that year.
