The Nativity scene and Christmas tree in St. Peter's Square will be inaugurated at 5 p.m., local time.
The Nativity scene is from Sutrio, a town near Venice. The tree is a 100-foot-tall spruce from Palena, a town of about 1,200 residents in Italy's Abruzzo region.
The Pope will not attend the event, but on Dec. 31, he usually goes to St. Peter's Square to admire it.
