Designed by Day and Klauder, with help from Ralph Adams Cram, to replace classrooms for the science departments and administration offices destroyed by fire in 1914, Green, Founders, and Pendleton were constructed over a twenty-year period as money allowed. Using the Collegiate Gothic Style, the architects dramatically sited the buildings along the escarpment at the center of the college. Green Hall, a bold, irregular composition that included innovations like the double-ridge roof, and Galen Stone Tower, a 180-foot shaft constructed of brick with limestone aggregate trim in a slender version of English Perpendicular style, dominate the group.
