Originally an Irish Catholic church by the name of St. Agnes, this church later became predominately African-American (as is the city of Detroit, where this is) and was re-named Martyrs of Uganda Catholic Church. It used to run a school, but now isn't even a church anymore, just an empty building. The building itself is beautiful. I used to live nearby. It's about a block north of the Motown Museum, on Rosa Parks, across the street from where my profile picture was taken.
I don't know if there used to be stained glass here - often when a church is closed, its fixtures will be salvaged and/or sold off by the diocese, for use in other churches, or for other uses. You can see a chain hanging from the ceiling, which would have at one time held a light fixture that was either salvaged or stolen. [Edit: oops, no you can't; must have been in one of my other photos. Still, I thought the comment was worth leaving.]
Lots of empty Detroit buildings have been looted. I remember some years ago reading an article about how an upscale community in Chicago had the lions on its gates that were stolen from the Lee Plaza building in Detroit - a perfectly salvageable building, unless it gets further vandalized or looted. That's just one example.
