The Old Classroom Building, Union College, located on College Street in Barbourville, Kentucky, is a historic building of Union College which was built in 1907. It was listed on the National Register of Historic Places in 1975.
A university official, in its 1974 NRHP nomination, suggests: "The design of the building as a whole by an as yet unknown architect is of somewhat anomalous stylistic character (perhaps vaguely Italian Romanesque in flavor), unassuming, but well-proportioned, and exactly calculated to fulfill the role of landmark that it does."
