Shew Hall, the original hospital structure, was built in 1867. It functions as the administrative building and is the focal point of the institution. This large structure is named in honor of the hospital's first superintendent, Dr. Abram M. Shew. Designed by Addison Hutton of Philadelphia, it was constructed in the Second Empire style. The building was remodeled in 1939, when the interior was updated and a flat roof bordered by a parapet was installed on the main section. The three large wings display mansard roofs and details that are indicative of the main section's former appearance.
