On the northern edge of the campus stand the Three Chapels, considered by many to be Brandeis's most influential architectural symbols. They express in their abstract form the Holy Scriptures of Western religion. This American Institute of Architects award-winning concept presents a different abstract shape for each of the three major Western faiths—Jewish, Catholic, and Protestant. Where the shapes of the Catholic and Protestant chapels are suggestive of books, the Jewish Chapel's shape is based on a scroll. Harrison and Abramovitz used a glazed, gray brick that sets the chapels apart from the red brick of most of the campus architecture. The chapels can be reached from the peripheral road or by walking across the Chapel Field.
