Seating 650, Lorimer is a venue for religious services, lectures, and concerts. It houses offices for chaplains as well as the small Rose Chapel. The Nickerson Carillon tolls the hour from the chapel tower.

Lorimer was the first building completed (in 1937) when Colby began its move from the downtown location to Mayflower Hill. Albert Schweitzer once gave a recital on the chapel's E.F. Walcker organ.
