Built by Austrian POWs during World War II
This structure, known in my family as the "Broadbent Building" stands along Highway 68/80, just east of the I-24 junction, near Cadiz, KY. I wrote about it several weeks ago, saying that I'd heard from several people that it was built by German POWs during World War II.
A local Prairie Bluestem reader, John, asked his dad about the building's history. John's dad grew up in that area and he personally remembered POW laborers on their farm and the Broadbent farm during World War II. John's dad also volunteered to ask the Broadbent family about the building's history.
Thanks to John and his dad, I can report with confidence that the Broadbent seedhouse was built by Austrian POWs (not by Germans.) The building's architects were Americans, however. I've updated the original post with all the details:
