5 /5 Marcus Pajda: I am not personally of the Catholic denomination, but I do love this cathedral! We go here with some regularity for "No-Name Chorale" concerts (a VERY talented, professional choir that does free concerts for the community - look them up!) and the Cathedral of Saint Peter graciously offers its space for the group to call home. Its such a magnificent piece of architecture and history in downtown Belleville.
If you are Catholic looking for mass in Belleville, or are interested in something like the NNC concerts or outreach programs the church runs, make a visit, its beautiful!
