. . . of Cincinnati
The Athenaeum of Ohio and Mt. St. Mary's Seminary of the West in Mt. Washington. About as far east and south as you can go and still be in the city limits.
The first wing, designed by Maginnis & Walsh, was completed in 1929 with the remaining section completed in the late 1950's. And no, I didn't go to enroll in the priesthood. But the details of the building are quite nice up close.
