In these first two photos, you can see the 1891 chapel to the right of the water tower. In these and the next three, the shot is taken from the direction of Oakland drive, looking west.
Below, a 1974 photo showing the water tower before restoration. (From "Images of America: Kalamazoo, Michigan" (Arcadia Pub., 2002))
Below is a view from the northwest corner of the interior of the quadrangle, pointing east, southeast.
