On March 6, 1889 the day before he died, Isaiah Williamson approved the purchase of 220 acres of land to be used for the school's campus in Middletown Township, near Elwyn, Pennsylvania. The site was selected from over 200 prospective locations, and the trustees acted quickly to secure the property and carry out Williamson's vision for the institution. The campus was later described by John Wanamaker as ""... gently rolling country with its springs and water courses, its broad pastures, its woodland acres of old oaks and chestnuts, its distant views of fertile farms, thriving towns—natural beauties enhanced by wise and not overdone landscape gardening, winding macadamized drives, and an artistic as well as convenient grouping of the various school buildings"".
