The balanced interior of Rollins Chapel, based on a system of four Roman arches, was decorated with a foliate motif. Window space was limited but carefully planned. The skylight and stained glass windows in the transepts, clerestory and apse were placed to affect maximum natural lighting.
The windows were concealed from view for several decades, revealed with much controversy in 2004. Considered works of art in their own right, the windows were designed and executed by craftsmen from Germany, Scotland, and America, including Louis Tiffany. Each window is dedicated to one of the College's previous presidents. With the sunlight streaming through the stained glass windows onto the stone and stained wood, the original interior was probably quite handsome.
