Old Coaly hauled limestone for Old Main (1850s) · Student-preserved skeleton as a Penn State founding artifact
Old Coaly was a mule brought to the Farmers' High School, the institution that became Pennsylvania State University, in the mid-1850s. The animal hauled limestone used in building Old Main, the campus's central administrative building. Old Coaly became a fixture of early campus life and a symbol of the school's agricultural origins.
After the mule died, students had the skeleton preserved as a tribute rather than disposed of, an unusual decision that turned the animal into a lasting campus artifact. Over the following decades the skeleton was moved among several buildings, including Watts Hall, before settling at the HUB-Robeson Center, the University Park student union, where it stands on the first floor near the gallery entrance.
The HUB-Robeson Center itself is the hub of student life at University Park. The Old Coaly display draws visitors as a curiosity and a connection to the university's nineteenth-century founding, and the skeleton's long history of being moved from building to building is the seed of the campus ghost lore attached to it.
Sources
The legend of Old Coaly follows the skeleton from building to building. In the rooms and halls where the preserved bones were stored, students reported hearing what sounded like hoofbeats moving down dark corridors, and others described the distinctive braying of a mule with no animal present. Penn State's own retelling of the campus's ghost lore includes Old Coaly among its best-known stories.
Student reporting adds that the ghost of the mule has been seen and heard at various spots around University Park, with the skeleton's current home in the HUB-Robeson Center described as a focal point for the tales. The accounts are presented as good-natured campus tradition rather than documented investigation.
Both the university's account and the student newspaper carry the story, giving it two independent retellings, but the lore remains the kind of long-standing campus legend that is not tied to dated, verified incidents.

State College, PA
Old Botany, built in 1888, is the oldest standing building on Penn State's University Park campus. It sits near Old Main and across Pollock Road from the grave of George W. Atherton, the university's seventh president, who served from 1882 until his death in 1906. The building has housed the botany department and university offices.
Altoona, PA
The Altoona Railroaders Memorial Museum occupies the Pennsylvania Railroad's Master Mechanics Building, a brick structure built in 1882 within the Altoona Works. The building first held railroad administrative offices and the company's Test Department — its physical and chemical testing laboratories. The museum moved into the renovated building and held grand-opening ceremonies on April 25, 1998.
Lancaster, PA
Lancaster Central Market traces its origins to a public marketplace chartered on this site by King George II on May 1, 1742; an earlier informal market dates to 1730. The current Romanesque Revival market house at 23 North Market Street was designed by architect James H. Warner and built in 1889. The building was listed on the National Register of Historic Places in 1972 and is operated by the Central Market Trust, a 501(c)(3) nonprofit, following a transfer in 2005.
