Lecture Hall, which is Penn State Shenango's oldest building, is now the official entrance to the campus. Built in 1903, Lecture Hall was originally constructed as the city of Sharon’s Central School, combining many of the community’s one-room schoolhouses.

During the most recent renovation, Lecture Hall underwent major reconstruction, including window replacements; electrical, heating and cooling upgrades; and renovation of the campus' art gallery.

Since fall 2006, Lecture Hall has housed the Admissions Suite and has served as the first point of contact for visitors to the campus.
