Update: I revisited the church and school in May of 2022.
I went by the old St. Mark’s Roman Catholic Church on Page Boulevard at Academy Avenue. It looks much like it did the last time I visited, but I think more of the window tracery (the wood framing) in the tower is missing.
The school building is huge, and shows how large this parish used to be. The congregation that bought the church after the parish closed has now moved on, as well.
