Est. 1857 · National Register of Historic Places (1975, ref. 75001645) · Civil War Union military hospital (post-Gettysburg, July 1863) · Original F&M literary-society hall
Diagnothian Hall was constructed in 1857 as the home of the Diagnothian Literary Society, one of two student literary societies at Franklin & Marshall College; Goethean Hall, identical in size and stepped-gable profile, was built simultaneously to house the rival Goethean Society. Both halls flank Old Main as part of a unified Gothic Revival ensemble on the rise overlooking the western edge of mid-nineteenth-century Lancaster. The Wikipedia entry on the trio describes the flanking halls as '2+1/2 stories tall, with steeply pitched gable roofs and stepped gables.'
During the American Civil War, all three Franklin & Marshall buildings—Old Main, Goethean, and Diagnothian—were pressed into service as a Union military hospital. The campus received significant numbers of wounded soldiers following the Battle of Gettysburg in July 1863, with Lancaster's rail connection to the battlefield site making it a logical receiving point for casualties. After the war the buildings resumed their academic role as literary-society houses.
The building was added to the National Register of Historic Places on July 30, 1975 (reference 75001645) alongside Old Main and Goethean Hall. It remains an active F&M academic and event space today.
Sources
The most-cited Diagnothian Hall account in the F&M Library Archives' Fast Facts page on campus ghost stories involves an unnamed music professor working alone in his office in the building late one night. According to the archive, while playing a recording of World War I-era music, the professor heard 'moaning, rattling sounds, and overall, the sounds of a person in intense pain' from the lobby outside his office. The sounds reportedly stopped when he left to investigate the empty lobby. In a separate later session, playing a Gettysburg-themed composition reportedly produced the same auditory phenomena, leading the archive's narrator to tie the experiences to the building's Civil War hospital era.
The archive also notes that staff have reported 'doors slamming with no one in the building and other strange occurences' inside Diagnothian. Wikipedia's 'Reportedly haunted locations in Pennsylvania' entry lists Old Main, Goethean Hall, and Diagnothian Hall collectively, with their hauntings attributed in popular folklore to Civil War soldiers who died during their treatment in the makeshift campus hospital.
No formal paranormal investigation has been published on Diagnothian Hall. The lore is institutional campus folklore catalogued by the college's own archive, anchored by the well-documented Civil War hospital usage.

Old Main is the historic central building of Franklin & Marshall College, constructed in 1854-1856 in the Gothic Revival style by the architectural firm Dixon, Balburnie, & Dixon. Together with Goethean Hall and Diagnothian Hall, it was added to the National Register of Historic Places on July 30, 1975 (reference 75001645). The building sits on or immediately adjacent to Lancaster's pre-1834 Gallows Hill, the county's public-execution site, and served as a Civil War-era military hospital alongside its companion halls.

Gettysburg, PA
Gettysburg College, founded in 1832 as Pennsylvania College, occupied much of its current campus during the Battle of Gettysburg in July 1863. Pennsylvania Hall served as a Confederate field hospital. Stevens Hall, completed in 1868, is the fourth-oldest building on campus. The former Theta Chi house at 339 Carlisle Street was converted to academic use in 2013.
