I went to the website and found out what that strange round structure is out front.
Some members of the parish gave the cathedral some bas-reliefs (done in a 30s style but thankfully not the Socialist Realism of Rockwell Kent) from an old store that was wrecked out in downtown Portage. So they built that strange incinerator-looking thing to display them.
That's "Commerce" and "Agriculture" - on the other side are "Industry" and "Art" - looking like nothing so much as a 1930s version of Achilles (although he's holding a caduceus so he ought to be Hermes) and Marianne (the symbol of France - although she's holding a little Nike so she ought to be Athena). But the Nike, not the wreath she's holding, ought to have the wings. The symbolism is a terrible mish-mash.
On the website they have some folderol about the bas-reliefs representing the church's duty to serve all diverse people, but that sounds like "somebody we don't want to offend gave us these and we have NO idea what to do with them, or say about it."
Clearly these folks don't plan well in any respect.
