ST. LOUIS, MO (KTVI) – On Sunday, hundreds gathered for a “Mass Mob” at St. Mary of Victories Catholic Church near downtown St. Louis. The 170-year-old church hosted the 6th mob since April 2015 on an important day in the church, Palm Sunday.

The goal of these events is to draw more people to a church than usually attend so others can learn of its history and significance to a community. It is an effort that is especially important since St. Louis has lost historic churches to demolition, most recently St. Bridget of Erin Church on North Jefferson.

Parishioners say keeping the churches active and thriving is the key to a successful community.

St. Mary of Victories Catholic Church is the second oldest church in the city of St. Louis, behind the Basilica of St. Louis, King, better know as the Old Cathedral. The first Mass Mob was held at the Most Holy Trinity Church in north St. Louis in 2015.
