The South Cloister was virtually the last part of the Chapel to be completed. Within its bays are a variety of special stones, including a rough stone from the prison at Rouen, where Joan of Arc was imprisoned. In the desk of the outdoor pulpit is the granite stone from which Bohemain religious reformer John Huss preached outdoors in the town of Kozi Hradeck when he was forbidden to speak in the churches of Czechoslovakia in 1413-1414. In a center bay are the names and dates of deceased Chapel workmen.

Just outside the Cloister is the Chapel's South Garden, given in memory of G. Keith Funston's father, George Edwin Funston. Designed by landscape architect Robert Zion of New York City, this garden was dedicated in 1965. Its sundial is early 19th-Century English.

On the north side of the Chapel is the Memorial Garden in which members of the College  community may have their ashes placed after cremation. The cross on the wall of the Chapel above the garden with its Latin inscription was given in memory of former College Trustee Seymour Smith '34 by members of his family.
