Volunteers play an essential role at the Mercer Museum and Library & Fonthill Castle, operated by the Bucks County Historical Society. Without volunteers we would not be able to maintain the quality and scope of programs and operations that allow us to serve an evergrowing and diverse audience. A variety of volunteer and internship positions are available.
Both Mercer Museum and Fonthill Castle have permanent exhibits that bring history to life.
