The Hollow Earth Festival
The 3rd Annual Hollow Earth Festival in Hamilton, Ohio, is a multi-faceted heritage event designed as a “Living Laboratory.” Scheduled for April 25, 2026, it blends local folklore, rigorous history, and hands-on science.
Here is what guests can expect to experience:
Education & STEAM Activities
The festival features a dedicated area for learning that aligns with the “Ohio Moves” theme. Highlights include:
Canal Engineering: A STEM activity inspired by the nearby former Miami-Erie Canal.
Aviation Heritage: A hot air balloon display paying tribute to Ohio’s legacy of flight.
Ancient Engineering: Exhibits showcasing Indigenous relics and the sophisticated design of local earthworks like Fortified Hill.
Entertainment & Atmosphere
Beyond the history, the event offers a vibrant festival atmosphere:
Live Performances: A lineup of live music and circus performers.
Animal Exhibits: Interactive live animal displays.
Historic Setting: Activities are centered around the Hollow Earth Monument in Symmes Park, the final resting place of visionary John Cleves Symmes Jr.
Recognition of Visionaries & Veterans
The heart of the event is the honoring of local figures who represent resilience and ingenuity:
James McBride: Mapmaker and “Renaissance Man.”
Dr. Julia Goodman: Hamilton’s first female physician.
Fred Brown & Celia Duerr: Veterans representing the Vietnam War and WWII eras, respectively.
🇺🇸 Alignment with the U.S. Semiquincentennial (250th Anniversary)
The festival serves as a local anchor for the national 250th-anniversary celebrations. It connects the local “Hollow Earth” folklore and Hamilton’s history to the broader American narrative in several ways:
Themes of Progress: By celebrating “2,500 years of Ohio innovation,” the event frames the American story as one of continuous ingenuity, from ancient earthworks to modern STEAM.
National Integration: It officially joins the national Semiquincentennial by highlighting American progress and “intellectual movements.”
Legacy of Exploration: The event honors the “uniquely American landmark” of the Hollow Earth Monument, celebrating the “bold imagination” that has defined the community since before the nation’s founding.
