Have you ever noticed the banners that hang in the library as you come in? They are based on historic stained glass windows, some of which you can see in a wall of the Kiefer Room on the ground floor. The windows originally were in a building that stood where Hartwell Hall is today, and were class gifts to the school back in the WWI era.
When the old building was torn down and replaced by Hartwell, the windows were removed, boxed up and stored in a boiler room! They were found down there 30 some years later and mounted in rooms in the library. You can learn lots more about the history of the school at our college archives site.
