About

Celebrating the weird and fascinating history of Hamilton, Ohio, the annual festival event is founded in 2024, with historical discussions, STEM/STEAM demonstrations and experiments, food trucks, and festive beer selections. John Symmes was not only a soldier in the War of 1812, but a visionary who devised a theory on the earth being hollow. His now debunked concept of a hollow earth, drew the imagination of Jules Verne, who wrote about it in "Journey to the Center of the Earth."
