It looks as though Sacred Heart church, at South 34th Street and Shawnee (south of the Kaw, and south of the Argentine District) in Kansas City, Kansas, was built in the 1940s or early 1950s or so. I didn't see a cornerstone when I drove by it last week on my resumed tour of 'Dotte parishes (which, actually, doubled as an excuse to take the little Curmudgeons out for hamburgers at Fritz's Railroad Cafe--Wyandotte county's best dining experience for anyone under 10).
So far in my tour, it's the newest of the Wyandotte County churches that is potentially on the chopping block. From the outside, it looks a lot like a gym. I didn't get a look inside, however. I don't have any history on Sacred Heart. I wonder if it was the original church, but I really doubt it. The neighborhood seems a fair bit older than the church, and It's hard to tell whether, in looking at the building, the church was intended to serve for a while as a church and then be converted into a gymnasium at a later time when they raised money for a church, or whether the church was originally a gymnasium and converted into the church when the old one was deemed to be inadequate.
Anyways, architecturally, Sacred Heart would be little loss to the diocese; however, it does seem to be some distance from its two neighboring parish churches, Holy Name (in the Turkey Creek bottoms along Southwest Boulevard) and St. John the Evangelist (in the Argentine neighborhood), so it would certainly be hard on the folks in that neighborhood to lose their parish.
Again, I renew my call for more information. If you know a little history of Sacred Heart, please fill us in!
