Jadwin and Fine Halls stand just west of Palmer Stadium and southwest of Peyton Hall and are connected by a joint library located beneath the plaza between them. Counting the two levels beneath the plaza, Jadwin Hall has altogether six floors, containing ninety laboratories, eighty-four offices, and eight classrooms. On the main floor is a meeting room for the physics faculty named for Princeton's first physicist, Joseph Henry, and adjacent to it a lounge named for its donor, Peter A. Ballentine '35.
Jadwin Hall was designed by Hugh Stubbins & Associates of Cambridge, Massachusetts. Its basic construction, like Fine Hall's, is of reinforced concrete and steel, and the principal exterior materials are Canadian granite and brick. The plaza is paved with a stone known as London Walk.
